Hi, here's your problem today. This problem was recently asked by Facebook:
Given a list of numbers, where every number shows up twice except for one number, find that one number.
Example: Input: [4, 3, 2, 4, 1, 3, 2] Output: 1 Here's the function signature:
def singleNumber(nums): # Fill this in. print singleNumber([4, 3, 2, 4, 1, 3, 2]) # 1
Challenge: Find a way to do this using O(1) memory.
