CombineLists - JavascriptModule0

// Combine Lists
// Write a program that reads two lists of numbers and combines them by alternatingly taking elements:

// combine 1,2,3 and 7,8,9 -> 1,7,2,8,3,9
// you can assume that the input lists will have the same length.
// Print the resulting combined list to the output, separating elements with a comma.

// Input
// On the first line you will receive the first list.
// On the second line -> 2nd list.
// Output
// On the only line of output, print all the numbers in format n1,n2,n3,..n
// Input
// 2,3,1
// 5,2,3
// Output
// 2,5,3,2,1,3
const input = ['2,3,1', '5,2,3'];
const print = this.print || console.log;
const gets = this.gets || ((arr, index) => () => arr[index++])(input, 0);

const secondArr = gets().split(',');

for (let i = 0; i < firstArr.length; i++) {
  combinedArr.push(firstArr[i]);
  combinedArr.push(secondArr[i]);
