You are given an array of integers. The problem statement says that you have to find out the most frequent element present in an array. If there are multiple values that occurs the maximum number of times, then we have to print any of them. Example Input [1, 4,5,3,1,4,16] Output …
In evaluate division problem we have given some equations, in the form, A/B = k, where A and B are strings and k is a real number. Answer some queries, if the answer does not exist return -1. Example Input: equations: a/b = 2.0 and b/c = 3.0 queries: a/c …
Prim’s algorithm is used to find the Minimum Spanning Tree(MST) of a connected or undirected graph. Spanning Tree of a graph is a subgraph that is also a tree and includes all the vertices. Minimum Spanning Tree is the spanning tree with a minimum edge weight sum. Example Graph Minimum …
In the sudoku solver problem we have given a partially filled (9 x 9) sudoku, write a program to complete the puzzle. Sudoku must satisfy the following properties, Every number(1-9) must appear exactly once in a row and once in a column. Every number(1-9) must appear exactly once in a …
If we have performing addition on a given range of array whose element values updated any time. Then in that type of problem, we handle using a segment tree structure. Given an array a[] with n elements and you have to answer multiple queries, each of the queries is one …
