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 ...

Red-Black TreeA Red-Black Tree should satisfy the following four conditions: It is a binary search tree. The root and leaves are black. There are no two consecutive red nodes. Every path from a node to its leaf nodes has the same number of black nodes. InsertionWhen inserting a node, the default color is red. If the inserted node is the root, change it to black. If the inserted node’s uncle is red, recolor the parent, uncle, and grandparent (f, u, g) to maintain balance, with g becoming ...
