Given a Rooted Tree with n node, labeled from 1 to n and tree is rooted at node 1. Parent of i-th node is p[i], i is starting from 2 as 1 is always root node. Let f(L) denotes the smallest connected subgraph that contains all leaves L. The task is to count the number of ways to… Read More »
The number system is basically a representation of numbers in different forms and with different operators. The origin of the number system was a long time ago by our ancestors. Earlier they use the barter system until they don’t get introduced to Number System. They discover the method of counting. They might be used their fingers for counting… Read More »
Given an integer array arr[], the task is to find the number of triplets at distinct indices that can be removed from the array such that the mean remains the same as before. Example: Input: arr[]= { 8, 7, 4, 6, 3, 0, 7} Output: 3 Explanation: The mean of the array is (8+7+4+6+2+1+7)/7 = 5 On removal… Read More »
Given a non negative number, you are required to find whether or not the number can be composed from sum of some number of 7s, 5s and 3s i.e. if a number is of the format n=3x+5y+7z (x, y, z being non negative integers), if not print -1. If it is of the required format, print the number… Read More »
Given a positive integer N, the task is to construct an array of length N and maximize the value at index K such that the sum of all the array elements is at most M and the absolute difference between any two consecutive array elements is at most 1. Examples: Input: N = 3, M = 7, K… Read More »
