Returns the missing number from a sequence of unique integers in range [0..n] in O(n) time and space. The difference between consecutive integers cannot be more than 1. If the sequence is already complete, the next integer in the sequence will be returned. For example: Input: nums = [4, 1, 3, 0, 6, 5, 2] Output: 7 """ def find_missing_number(nums): missing=0 fori, numinenumerate(nums): missing ^= num missing ^= i+1 returnmissing .
