Suppose we have an array nums where the ith element indicates a bag containing nums[i] number of balls. We also have another value called mx. We can perform the following operation at most mx times −Select any bag of balls and divide it into two new bags with at least ... Read More

Suppose we have an array called points containing the coordinate points on a 2D plane, they are sorted by the x-values, where points[i] = (x_i, y_i) so x_i < x_j for all 1

Suppose we have a string s, we have to find the number of homogenous substrings of s. The answer may be very large, so return answer modulo 10^9+7. A string is said to be homogenous when all the characters of the string are the same.So, if the input is like ... Read More

Suppose we have a number n, indicates that there are n different courses labeled from 1 to n. We also have an array called relations where relations[i] contains a pair (prevCourse_i, nextCourse_i), representing a prerequisite relationship between the course prevCourse_i and the course nextCourse_i: so course prevCourse_i has to be ...

Suppose, we are given a graph that contains n vertices numbered 0 to n -1. The graph is undirected and each edge has a weight. So given the graph, we have to find out the critical and the pseudo-critical edges in the graphs MST. An edge is called a critical ... Read More

Suppose we have three values a, b and c. We are playing a solitaire game with three piles of stones whose sizes are a, b, and c respectively. Each turn the player selects two different non-empty piles, take one stone from each, and add 1 point to his score. The ... Read More

Suppose we have a string s with only three characters 'a', 'b', and 'c'. We shall apply the following algorithm on the string any number of times −Select a non-empty prefix from the s where all the characters in the prefix are same.Select a non-empty suffix from the s where ... Read More

Suppose we have an array called nums. We have to find the absolute sum of a subarray [nums_l, nums_l+1, ..., nums_r-1, nums_r] is |nums_l + nums_l+1 + ... + nums_r-1 + nums_r|. We have to find the maximum absolute sum of any subarray of nums (that subarray can possibly be ... Read More

Suppose we have a tree with n nodes that are numbered from 0 to n-1. The tree is given by a parent array, where parent[i] is the parent of node i. The root of the tree is node 0. We have to find the kth ancestor of a given node, ... Read More

Suppose we have an array of positive calues candiesCount where candiesCount[i] denotes the number of candies of the ith type we have. We also have another another array called queries where queries[i] has three parameters [favoriteType_i, favoriteDay_i, dailyCap_i]. We have some rules:We start eating candies on day 0.We cannot eat ... Read More
