## Traverse the given directory using BFS and DFS in Java

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.

Coding made easy

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.

Given a binary tree, write an iterative algorithm to print leaf to root path for every leaf node of binary tree. Use of Recursion is prohibited.

Given a sorted array of integers, find floor and ceil of a given number in it. The floor and ceiling map the given number to the largest previous or the smallest following integer, respectively.

Given a binary search tree, find a pair with given sum present in it.

Given a directed acyclic graph (DAG) and a source vertex, find the cost of shortest path from source vertex to all other vertices present in the graph.

Given a binary tree, write an efficient algorithm to compute maximum width of it.

Consider a directed graph where weight of itsÂ edges can be one of x, 2x or 3x (x is a given integer), compute the least cost path from source to destination efficiently.

Given a square matrix, print maximum length snake sequence in it. A Snake sequence is defined as a sequence of numbers where each new number, which can only be located to the right or down of the current number, is either plus or minus one.

Given an binary array of size two having alteast one element as zero, write a single line function to set both its elements to zero. Use of ternary operator and direct assignment of elements are not allowed.

In k-partition problem, we need to partition an array of positive integers into k disjoint subsets that all have equal sum and they completely covers the set.
