The isPalindrome function takes a string as an input and checks if the string is a palindrome. It splits the string into an array of characters and checks to see if the last character in the array is equal to the first character in the array. If the strings are not equal, the function returns false.

The useMouseDelta() function is used to animate the width of an element based on mouse movements. The function first initializes state variables to false values to indicate that no dragging is going on. Then, it uses useState() to store the current width of the element and the initial width. Using useRef(), the function stores the origin of the element as the currentWidth. The function then creates two callbacks, handleMouseDown and handleMouseUp. When a mouse event is received, the function sets the dragging state to true and calls the corresponding callback. The function then sets the result state to the currentWidth plus the mouse clientX position. Finally, the function returns the result state.

The df[df['column'].str.contains('filter')] function will return a boolean indicating whether the string 'filter' is found anywhere in the column value.

Filter a Pandas Dataframe column by string



The code reads a SQL statement from the file input. It uses the string concatenation operator (+) to define a list of column identifiers. It then passes that list to the read_sql() function, which will select all the columns from the table named table where the column identifier in the list matches the given identifier.

Read a sql table 'where in' as a Dataframe



The df.loc[df["column"].isin(list)] function searches the location of the given column in the dataset and returns a list of the rows that contain that column. This function is equivalent to:

This code creates a new table called "merged" that is a union of the two original tables. The first argument is the name of the table to be created, the second is the name of the table to be merged into it, and the third is the default merge method (which is "inner"). The fourth argument is a boolean that tells the merge function which table should be the "left" table and which should be the "right" table. The fifth argument is a string that tells the merge function which column to use as the "left" column and which column to use as the "right" column.

This code extracts the second lowest number from a list of numbers. It checks if the number is negative by subtracting 1 from it and comparing the result to 0. If the number is less than zero, the number is added to a list and the loop iterates again. If the number is greater than zero, the number is added to the list and the loop iterates again. The code then returns the list of numbers with the second lowest number in it.

findErrorNums.js


The code creates a map of integers to their corresponding num values. It then loops through the num values, calculating the distance between each two numbers. The code then returns the distance between each number and the original variable solution.

RandomNumerJSLength.js



The code is in the function called while. The code checks to see if the user entered anything after the --. If they did, it checks to see what command they entered. Once it knows what command to run, it uses the command to get the needed information. It uses the case command to switch between different commands. For example, if they entered --fingerprint, then it would use the shift command to change the case tofingerprint. After that, it checks to see if the Fingerprint option was chosen. If it was, it uses the CA_FINGERPRINT variable to get the fingerprint. If it wasn't, it goes to the next command.

The code in this package example defines a learning user function called fabonaccii(). This function takes an integer input argument, n, and returns an integer value for the function call. The fabonaccii() function first defines a variable called loop(), which will be used to hold a sequence of integers. The function loops through the input argument, x, counting from 1 up to but not including n. If x is greater than n, then the function returns the value of Last, which is the value of x + 1. If x is equal to n, then the function returns the value of NextLast, which is the value of x + Last. Finally, the function assigns the result of the loop() function to the variable, fabonaccii(). The value of fabonaccii() will be the sum of the values of 1, 2, and 3.

     // Initialize sum at 1
     // Each time go to next value if it is larger
     // Sum must be odd as Fibonacci series is odd
      // If n is even, reset and return last value
      // If it is not an odd number, reset and return the first value
      // return nth Fibonacci value
     def loop(x: Int, Last: Int, NextToLast: Int): Int = {

The code snippet will take a string x and convert it to a number. It will then look to see if x is less than zero and if it is, it will set isNegative to true and convert the number to a reverse string. The reverse string will then be divided by 2, multiplied by 31 and rounded down to return the original number.

This function converts a string s into an array obj of integers. The string s is divided into numRows sections, where each section is either a single character or a substring of the string that starts at the section number 2*numRows - 2 and ends at the section number before the current section.

The pattern is a 2*numRows - 2 array of numbers. The first numRows elements of the pattern are the section numbers. The second numRows elements of the pattern are the section numbers except for the first element, which is 1. The function checks if the section number passed in is in the pattern. If it isn't, the function returns the string s. Otherwise, the function iterates through the string s and grabs each character or substring that is a part of the section number in the pattern. The function also assigns that character or substring to the variable obj[row], if it exists. The function then returns the value of obj[row].join(''), which is the string that is stored in the variable result.

Zigzag conversion



The code creates a function that takes a string and returns the longest palindrome. It uses a variable, longestPalindrome, to store the length of the palindrome. The code first splits the string into an array of words. For each word, it creates an empty object, and assigns a value to each of the properties. For example, the property for index 1 would have a value of 1, and the property for index 2 would have a value of 2. Next, the code loops through the string, and for each word, it checks to see if the word is the same as the previous word. If it is, the value for the property for that word is set to 1. If the word is not the same as the previous word, the value for the property is set to 0. Finally, the code returns the string with the value of the longest palindrome stored at the position of the leftmost word and the length of the longest palindrome stored at the position of the rightmost word.

Longest Palindrome substring



The function finds the median of the arrays nums1 and nums2. It initializes an array called resArr to contain the median values. It compares each value in nums1 and nums2 to see if it is greater than or equal to the median value in resArr. If it is, the value is added to resArr and the index of the value in resArr is incremented. Otherwise, the value in nums2 is added to resArr and the index of the value in resArr is incremented. The function then returns the median of the values in resArr.

Median of two sorted arrays



This function takes as its only parameter a string and returns the length of the longest substring of that string.

First, the function creates an "empty" mapping object that will store the results of the function. The mapping object will be indexed by string position and will keep track of whether or not the string at that position has been marked as being in the result set.

Next, the function loops through the string and sets the mapping object entries for each character to true. This will mark the string as being part of the result set.

Next, the function determines the length of the longest substring and returns that value.

Length of longest unique substring



The code defines a function called add which takes two arguments, A and B.

The first two lines of code iterate through the characters in A and B, and collect the number of characters between them. 

The next three lines calculate the sum of the absolute value of each character. This is done to stop the sum from getting too large if there are lots of small numbers in the sum. 

The final line of code returns the sum.

Add two large numbers


package example

object reverseS extends App{
  println("hello world")

  def reverseString(word:String): String = {
    if (word.length ==1) return word
    else {
      //println("to reverse " +word+"-first i need to reverse-" + word.tail)
      var reversed = reverseString(word.tail) + word.

The code in this package example defines a method called factorial that takes an Int argument. The method prints "hello world" when executed. The code also defines a variable called factorial that stores the result of calling the factorial method on successive integers. The code in this example computes the factorial of 10- first, it prints "computing factorial of 10- first I need factorial of 9" and then it computes the factorial of 9 by multiplying 9 by 9 and storing the result in the variable result. Finally, the code prints the value of result.
