Program to find GCD or HCF of two numbers using Middle School Procedure in C++
In this tutorial, we will be discussing a program to find GCD or HCF of two numbers using Middle School Procedure.For this we will be provided with two numbers. Our task is to find the GCD (greatest common divisor) or HCF (highest common factor) for the given values.Example#include #define MAXFACTORS 1024 using namespace std; //structure to store factorization typedef struct{ int size; int factor[MAXFACTORS + 1]; int exponent[MAXFACTORS + 1]; } FACTORIZATION; void FindFactorization(int x, FACTORIZATION* factorization){ int i, j = 1; int n = x, c = 0; int k = 1; ...
Read MoreMaximum points from top left of matrix to bottom right and return back in C++
In this tutorial, we will be discussing a program to find maximum points from top left of matrix to bottom right and return backFor this we will be provided with matrix consisting of #-blocked path, *-points, .- allowed path. Our task is to go from one corner to another (right and below moves) and come back (left and top moves) such as to collect maximum pointsExample#include #define MAX 5 #define N 5 #define M 5 #define inf 100000 using namespace std; //calculating points int cost(char grid[][M], int row1, int col1, int row2, int col2) { if (row1 == ...
Read MoreWord Abbreviation in C++
Suppose we have an array of n unique strings, We have to generate minimal possible abbreviations for every word following rules below.Starting with the first character and then the number of characters abbreviated, which followed by the last character.If we find any conflict and that is more than one words share the same abbreviation, a longer prefix can be used instead of only the first character until making the map from word to abbreviation become unique.When the abbreviation doesn't make the word shorter, then keep it as original.So, if the input is like ["like", "god", "internal", "me", "internet", "interval", "intension", ...
Read MoreSerialize and Deserialize Binary Tree in C++
Suppose we have one binary tree and we have to serialize and deserialize them. As we know that the serialization is the process of converting a data structure or object into a sequence of bits so we can store them in a file or memory buffer, and that can be reconstructed later in the same or another computer environment.Here we have to devise an algorithm to serialize and deserialize binary tree. The binary tree is a rooted tree in which each node has no more than 2 children.So, if the input is likethen the output will be Serialize − 1 ...
Read MoreWord Squares in C++
Suppose we have a set of words (all are unique), we have to find all word squares and we can build from them. Here a sequence of words forms a valid word square if the kth row and column read the exact same string, where 0 ≤ k < maximum of numRows and numColumns. So as an example, the word sequence ["ball", "area", "lead", "lady"] will construct a word square because each word reads the same both horizontally and vertically.ballarealeadladySo, if the input is like ["area", "lead", "wall", "lady", "ball"], then the output will be [[ "wall", "area", "lead", "lady"], ...
Read MoreFind the largest Complete Subtree in a given Binary Tree in C++
ConceptWith respect of a given Binary Tree, the task is to determine the size of maximum complete sub-tree in the given Binary Tree.Complete Binary Tree – A Binary tree is treated as Complete Binary Tree if all levels are completely filled without possibly the last level and the last level has all keys as left as possible.It has been noted that all Perfect Binary Trees are Complete Binary tree but reverse in NOT true. It has been seen that if a tree is not complete then it is also not Perfect Binary Tree.Input 2 / \ ...
Read MoreFill 8 numbers in grid with given conditions in C++
Suppose we want to place 1, 2, 3, 4, 5, 6, 7, 8, into the eight circles in the given figure, in this way that no number is adjacent to a number that is next to it in the sequence.So, if the input is like0-1-10-1-1-1-10-1-10then the output will beTo solve this, we will follow these steps −N := 3, M := 4NOTCONSIDERED := -1Define a function present_in_grid(), this will take grid[N][M], num, for initialize i := 0, when i < N, update (increase i by 1), do:for initialize j := 0, when j < M, update (increase j by 1), ...
Read MoreFind median of BST in O(n) time and O(1) space in C++
ConceptWith respect of a given Binary Search Tree(BST), our task is to determine median of it.For even no. of nodes, median = ((n/2th node + (n+1)/2th node) /2 For odd no. of nodes, median = (n+1)/2th node.For given BST(with odd no. of nodes) is − 7 / \ 4 9 / \ / \ 2 5 8 10Inorder of Given BST will be : 2, 4, 5, 7, 8, 9, 10 So, here median will 7.For given BST(with even no. of nodes) is − 7 ...
Read MoreBinary Number with Alternating Bits in C++
Suppose we have a positive integer, we have to check whether it has alternating bits − so, two adjacent bits will always have different values.So, if the input is like 10, then the output will be True, as binary representation of 10 is 1010.To solve this, we will follow these steps −p := n AND 1if n < 2, then −return truen := n/2while n is non-zero, do −c := n AND 1if c XOR p is same as 0, then −return falsep := cn := n/2return trueLet us see the following implementation to get better understanding −Example#include using ...
Read MoreCount Binary Substrings in C++
Suppose we have a string s, we have to find the count of contiguous substrings that have the same number of 0's and 1's, and all the 0's and all the 1's in these substrings are grouped consecutively. If substrings occur multiple times are counted the number of times they occur.So, if the input is like "11001100", then the output will be 6, as the substrings are "1100", "10", "0011", "01", "1100", "10".To solve this, we will follow these steps −Define an array cnt of size 2 and fill this with 0res := 0for initialize i := 0, when i ...
