Write a function that moves all the zeroes to the end of an array. Do this without returning a copy of the input array.

Examples

 zeroesToEnd([1, 2, 0, 0, 4, 0, 5]) ➞ [1, 2, 4, 5, 0, 0, 0]  zeroesToEnd([0, 0, 2, 0, 5]) ➞ [2, 5, 0, 0, 0]  zeroesToEnd([4, 4, 5]) ➞ [4, 4, 5]  zeroesToEnd([0, 0]) ➞ [0, 0]

Notes

  • You must mutate the original array.
  • Keep the relative order of the non-zero elements the same.

Solution:

 1  2  3  4  5  6  7  8  9 10 11
 
function zeroesToEnd(a) {   let len = a.length;   for (let i = 0; i < a.length; i++) {     if (a[i] == 0) {       a.splice(i, 1);       i--;     }   }   a = [...a, ...Array.from({ length: Math.abs(a.length - len) }, () => 0)];   return a; }
