LeetCode 2501. Longest Square Streak in an ArrayThe task requires us to find the longest subsequence in an integer array where each element, after sorting, is the square of the previous element, with a minimum length of two elements. A subsequence, in this context, is a sequence derived from the array by removing zero or more elements while keeping the remaining elements in the same order. If there is no such subsequence, we should return -1. Key observations: The problem’s main requirement is ...
