Given a directed acyclic graph (DAG), print it in Topological order using Kahn’s Topological Sort algorithm. If the DAG has more than one topological ordering, print any of them.
Given an integer, swap adjacent bits of it. In other words, swap bits present at even positions with those present in odd positions.
Given a BST and a valid range of keys, remove nodes from BST that have keys outside the valid range.
Given a sequence of numbers such that the difference between the consecutive terms is constant, find missing term in it in O(log(n)) time.
In this post, we will see how to find all lexicographic permutations of a string where repetition of characters is allowed.
In this post, we will discuss division of two numbers (integer or decimal) using Binary Search Algorithm.
Given an array of integers, find subarrays with given sum in it.
Given a M x N binary matrix, fill it with alternating rectangles of 0 and 1.
Find all N-digit binary numbers with equal sum of left and right half. N varies from [1-9] and binary number should not start with 0.
In this post, we will see how to traverse the given directory and list out all files present in it and all its sub-directories.
Given a set S, generate all distinct subsets of it i.e., find distinct power set of set S. A power set of any set S is the set of all subsets of S, including the empty set and S itself.
Given a string, find minimum cuts needed to partition it such that each partition is a palindrome.
