    The code in this function rotates an array by a certain amount every time it is called. It starts at position 0, and increments the index by 1 for each call. It then uses the reduction operator to modify the target array to reflect the new position of the index.

    function circularArrayRotation(a, k, queries) {
      //Enter your code here
      return queries.map(value => a.reduce((target, item, index) => {
        let focus = (index + k) % a.length;
        target[focus] = item;
    
        return target;
      }, [])[value]);
    }
