The elves are receiving strange binary messages from Mars πŸͺ. Are the aliens trying to communicate with them? πŸ‘½

The message that arrives is an array of 0s and 1s. It seems they have found a pattern… To make sure, they want to find the longest segment of the string where the number of 0s and 1s is equal.

findBalancedSegment([1, 1, 0, 1, 1, 0, 1, 1])
//                         |________|
// position of segment:    [2, 5]
// longest balanced
// of 0s and 1s

findBalancedSegment([1, 1, 0])
//                      |__|
//                     [1, 2]

findBalancedSegment([1, 1, 1])
// no balanced segments: []

Keep in mind that if there is more than one balanced pattern, you should return the longest and the first one you find from left to right.

They say that if they find the pattern, they will be able to send a message back to Mars πŸš€. It seems that they have to send it to
