beautifulArray.js

Rahman Niftaliyev

This code constructs an array of numbers and checks to see if the array is "beautiful" by comparing the length of each element with the range of numbers provided. The function isBeautifulArray compares the length of the array elements against a provided range, and returns a boolean value.

function arrayConstructor(paramsArray, number2, params2Number) {
  while (number2 <= params2Number) {
    if (number2 <= params2Number) {
      paramsArray.push(number2);
    } else {
      break;
    }
  
    number2 *= 2;
  }
  
  return paramsArray;
}
  
function isBeautifulArray(paramsNumber) {
  let initialArray = [];
  
  arrayConstructor([], 1, paramsNumber).forEach((item) => {
    `${item}`.split("").forEach((item2) => {
      initialArray.push(item2);
    });
  });
  
  let isBeauty = true;
  
  initialArray.forEach((item, index, arraySelf) => {
    if (arraySelf.indexOf(item) !== arraySelf.lastIndexOf(item)) {
      isBeauty = false;
    }
  });
  
  console.log(initialArray);
  console.log(isBeauty);
  
  return parseInt(isBeauty);
}
  
isBeautifulArray(16);
