## Print all distinct Subsets of a given Set

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.

Coding made easy

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 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 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.

3-partition problem: Given a set S of positive integers, determine if it can be partitioned into three disjoint subsets that all have same sum and they cover S.

In this post, we will see how to sort an array of integers using iterative merge sort algorithm. Merge sort is an efficient sorting algorithm which falls under divide and conquer paradigm and produces a stable sort.

Given an unsorted array of integers whose each element lies in range 0 to n-1 where n is the size of the array, rearrange array such that A[A[i]] is set to i for every element A[i] in the array.

Given an array of integers, duplicates appear in it even number of times except two elements which appears odd number of times. Find both odd appearing element without using any extra memory.

Given an array representing a Min Heap, convert Min Heap into a Max Heap. The conversion should be done inplace and in linear time.

Given an array, reverse every group of consecutive m elements in given subarray of it.

Given an array of integers, find a subset in it that has maximum product of its elements.

Given an unsorted array of integers, print all pairs with given difference k in it without using any extra space.
