removeDuplicates

Given an array of integers, return a new array containing the same integers. However, if a value appears more than once in an array, the new array should contain only the first occurrence of that value.

removeDuplicates([3, 4, 1, 3, 5]) → [3, 4, 1, 5]
removeDuplicates([1, 1, 2, 1, 2, 2, 1, 2]) → [1, 2]
removeDuplicates([5, 6]) → [5, 6]
