Maximum segment value after putting k breakpoints in a number in C++
In this problem, we are given a string that denotes a large number and an integer k roar denotes the number of breakpoints. Our task is to create a program that will find the maximum segment value after putting L breakpoints in a number.Here, we have to find the maximum number that can be generated after putting k breakpoint in the number given by the string.Let's take an example to understand the problemInput − string = “45972”, k = 3Output − 97Explanation −All possible number is: 45 9 7 2 4 59 7 2 ...
Read MoreMaximum removal from array when removal time >= waiting time in C++
In this problem, we are given an array of N elements. Our task is to find the maximum removal from the array when removal time >= waiting time.So, here we will be removing the elements of the array. The value of the element of the array denotes the removal time(time taken to remove the element from the array).The element has a waiting time which is the time it will have to wait till it will get removed.The element can be removed from the only if the removal time is greater than the time it has to wait.We have to find ...
Read MoreMaximum size subset with given sum in C++
Problem statementGiven an array of N elements and sum. We need to find size of maximum size subset whose sum is equal to given sumExampleIf input array is arr = { 2, 3, 5, 10 } and sum = 20 then output will be 4 as −2 + 3 + 5 + 10 = 20 which is equal to given sumAlgorithmWe can use dynamic programming to solve this problem.To count the maximal subset, we use another DP array (called as ‘count array’) where count[i][j] is maximal of.count[i][j-1]. Here current element is not considered.scount[i- X][j-1] + 1. Here X is value ...
Read MoreMaximum spiral sum in Binary Tree in C++
In this problem, we are given a binary tree. Our task is to create a program that will find the maximum spiral sum in a binary tree in C++.Spiral sum of a binary tree is the sum of nodes that are encountered in the spiral traversal of the binary tree.In the spiral traversal of a tree, the nodes are traversed from the root to the leaf node. The traversal takes place from left to right then for the next level from right to left and so on for the further levels.Example −Output −5Explanation −We will consider the spiral traversal until the ...
Read MoreConvert Hexadecimal value String to ASCII value String in C++
In this tutorial, we will be discussing a program to convert hexadecimal value string to ASCII value string.For this we will be provided with a string with some hexadecimal values. Our task is to get that hexadecimal value and convert it into equivalent ASCII values.Example#include using namespace std; string convert_ASCII(string hex){ string ascii = ""; for (size_t i = 0; i < hex.length(); i += 2){ //taking two characters from hex string string part = hex.substr(i, 2); //changing it into base 16 char ch = stoul(part, nullptr, 16); //putting it into the ASCII string ascii += ch; } return ascii; } int main(){ cout
Read MoreConvert min Heap to max Heap in C++
In this tutorial, we will be discussing a program to convert min heap to max heap.For this we will be provided with the array representation of the min heap. Our task is to convert that given min heap to max heap in O(n) time complexity.Example#include using namespace std; //converting a given subtree into a heap void convert_arrayheap(int arr[], int i, int n){ int l = 2*i + 1; int r = 2*i + 2; int largest = i; if (l < n && arr[l] > arr[i]) largest = l; if (r < ...
Read MoreConvert singly linked list into circular linked list in C++
In this tutorial, we will be discussing a program to convert a singly linked list into circular linked list.For this we will be provided with a singly linked list. Our task is to take the elements of that list and get it converted into a circular linked list.Example#include //node structure of linked list struct Node { int data; struct Node* next; }; //converting singly linked list //to circular linked list struct Node* circular(struct Node* head){ struct Node* start = head; while (head->next != NULL) head = head->next; //assigning start to the ...
Read MoreConvert singly linked list into XOR linked list in C++
In this tutorial, we will be discussing a program to convert a singly linked list into XOR linked list.For this we will be provided with a singly linked list. Our task is to take the elements of that list and get it converted into a XOR linked list.Example#include using namespace std; //node structure of linked list struct Node { int data; struct Node* next; }; //creation of new node Node* newNode(int data){ Node* temp = new Node; temp->data = data; temp->next = NULL; return temp; } //printing singly linked list void print(Node* head){ ...
Read MoreConvert String into Binary Sequence in C++
In this tutorial, we will be discussing a program to convert string into Binary sequence.For this we will be provided with a string of characters. Our task is to convert each of the character into its binary equivalent and print it out spaced between for different characters.Example#include using namespace std; //converting into binary equivalent void convert_binary(string s){ int n = s.length(); for (int i = 0; i 0){ (val % 2)? bin.push_back('1') : bin.push_back('0'); val /= 2; } reverse(bin.begin(), bin.end()); cout
Read MoreConvert Ternary Expression to a Binary Tree in C++
In this tutorial, we will be discussing a program to convert ternary expression to a binary tree.For this we will be provided with a ternary expression. Our task is to convert the given expression in the form of a binary tree depending upon the various paths(choices) possible.Example#include using namespace std; //node structure of tree struct Node { char data; Node *left, *right; }; //creation of new node Node *newNode(char Data){ Node *new_node = new Node; new_node->data = Data; new_node->left = new_node->right = NULL; return new_node; } //converting ternary expression into binary tree Node *convertExpression(string ...
