Unordered array complexity

WebIf it does, then we have seen this prefix sum before. That means we must have a zero-sum array. So, return true. - A match with prefix sum was not found: So, insert the prefix sum into the set. - You never found a zero-sum sub-array; so, return false. Your code must have complexity O (n), where n is the length of the input WebIn problem F, I also sort the array in descending order and then I made a prefix sum of n elements. (Let's call it p) We have 3 situations: ... While it's true that unordered_set is faster than set on average, the worst case time complexity of unordered_set can get to O(n^2) instead of O(log n) in a normal set ...
