It is the simplest task of the set. The solution is based on greedy algorithmm. First of all, we need to zero outa1. One needs to makea1steps withi = 1and someton each step. Whichtis the most efficient? Th

I am looking for a O(nmlogk)O(nmlogk) solution. Are there any smart data structures? Note that when A=[1,2,3]A=[1,2,3], all intervals are legal. For example, [1,2][1,2] is legal, as both 11 and 22 appear once. We do not care about 33 because 33 does not appear. ...

This problem was asked in recent CodeNation Online Test — Please give your solution idea to it Given A,B,C — Count the number of valid arrays of size "A"; such that each number of the array is in the range [1,C]; and no subarray of length > B exists in the valid array such...
Part 1: Wait, who the fuck is EndlessDreams? I mean, he is the first thing that appears when you open the TheForces group, he must be pretty important, right? In addition, his solution to E onCodeforces Round 960 (Div. 2)(over thehololgram-sakuraalt) was considerably different from...

Algorithm to solve this problem — If all weights were distinct solution is pretty simple — find 'r' the last and only occurrence of smallest number in the weight array — now travel efficiently through the second smallest number and push it to smallest position > r -> now do the same ...
Can anyone propose a solution? We have a N <= 100,000 node rooted tree. All nodes have integer weights (**and each weight is between 0 and 1000**). Let the height of the tree be the longest path to a leaf from the root (and the root is just defined to be node 0). The "lo...
