Minimize zeroes Recursion Challenge

Given an array of numbers, return a new array where each consecutive run of zeroes is reduced to a single zero. Non-zero values and separate groups of zeroes should each retain one zero.

Function Signature

minimizeZeroes(array)

Parameters

• array — an array of numbers.

Output

Return a new array with consecutive duplicate zeroes collapsed.

Constraints

• The function must use recursion.
• The input array must not be mutated.
• The function should accept exactly one argument.

Examples

minimizeZeroes([2, 0, 0, 0, 1, 4])       → [2, 0, 1, 4]
minimizeZeroes([2, 0, 0, 0, 1, 0, 0, 4]) → [2, 0, 1, 0, 4]
