C Algorithm - Evaluation of Postfix Expression - Data Structure -Given a string, reverse it using stack. For example “GeeksQuiz” should be converted
Category - c programming
Convert a BST to a Binary Tree such that sum of all greater keys is added to every key - Given a Binary Search Tree (BST), convert it to a Binary Tree.
C Algorithm -Introduction to Stack - Data Structure -Stack is a linear data structure which follows a particular order in which the operations
The idea is to use Reservoir Sampling. Following are the steps. This is a simpler version of Reservoir Sampling as we need to select only one key.
It is quite easy to visualize this statement since the median which we report will be (k/2)th element and if we take k/2 elements from the left quarter.
Given an unsigned integer, swap all odd bits with even bits. For example, if the given number is 23 (00010111), it should be converted to 43 (00101011).
C Programming - Binary representation of a given number - Bit Algorithm - Write a program to print Binary representation of a given number.
C Program to find whether a no is power of two - Bit Algorithm - Given a positive integer, write a function to find if it is a power of two or not.
C Programming - Find if there is a path between two vertices in a directed graph - check whether there is a path from the first given vertex to second.
C Programming - Matrix Chain Multiplication - Dynamic Programming MCM is an optimization problem that can be solved using dynamic programming.
