Sort a list regarding the occurance of each element in a list.
Best preparation would be solving Leetcode questions under time constraint. Also practice talking out loud the thought process when solving these questions.
Given an integer array, can you delete at most one element such that the rest of the array is sorted?
In Today’s class, Chef is here to teach students about Trees. Tree is a a connected graph of N nodes and N-1 edges. After class, Chef gave them an assignment to complete. Assignment is as follows :- Given a tree with single node (root), we need to find whether we can build a tree with exactly N leaf nodes by applying given queries. Query 1 : Choose any i in between 2 to K and any leaf node say L in current Tree, attach i leaf nodes to L. (We can choose any particular i only once) Query 2 : Choose an existing edge of Tree and cut the edge. Remove the entire sub-tree attached with that edge. Students need to answer T independent test cases. Can you help them ? Example • If K = 5, N = 6. One possible way to build a tree with N = 6 leaf nodes is :- o Query 1:1 = 5, leaf node = root. Now, there are 6 nodes in tree and 5 leaf nodes. o Query 1 : 1 = 2, choose any of the 5 leaf nodes. Now, there are 8 nodes in tree an leaf nodes. • If K = 2, N = 3. It is not possible to build tree with 3 leaf nodes using given queries. Function Description •K: Represents the maximum value of i allowed in Query 1. •N: Represents the required number of leaf nodes.
