## Kahn’s Topological Sort Algorithm

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.

Coding made easy

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.

Implement Quick sort algorithm usingĀ Hoare’s Partitioning scheme.

Given a collection of n items, each of which has a non-negative integer key whose maximum value is at most k, effectively sort it using counting sort algorithm.

In this post, we will implement KMP Algorithm in C, C++ and Java programming language.

Given a BST, write an efficient function to delete a given key in it.

Given a BST, write an efficient function to search a given key in it. The algorithm should return the parent node of the key and print if the key is left or right node of the parent node. If the key is not present in the BST, the algorithm should be able to determine that.

A Binary Search Tree (BST) is a rooted binary tree, whose nodes each store a key (and optionally, an associated value) and each have two distinguished sub-trees, commonly denoted left and right. The tree should satisfy the BST property, which states that the key in each node must be greater than all keys stored …

Given a binary tree, write iterative and recursive solution to traverse the tree using in-order traversal in C++ and Java. Unlike linked lists, one-dimensional arrays and other linear data structures, which are traversed in linear order, trees may be traversed in multiple ways in depth-first order (pre-order, in-order, and post-order) or breadth-first order (level …

Given a binary tree, print its nodes level by level. i.e. all nodes present at level 1 should be printed first followed by nodes of level 2 and so on.. All nodes for any level should be printed from left to right.

Given a linked list, sort it using merge sort algorithm. Merge sort algorithm is an efficient, general-purpose sorting algorithm which produces a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output. Merge sort is a comparison sort, i.e. it can sort items of any …
