Finding all Subsets of a given set

Hi Geeks! Welcome to 100 Days Leetcode Challenge. Day 3 In this article, I'll explain about how to find all the subsets of a given set(power set). Here is our given problem, Given a set of distinct integers, nums, return all possible subsets. Note: The solution set must not contain duplicate subsets. Example: Input: nums = [1,2,3] Output: [ [3], …

C# Program to Reverse Integer

Given a 32-bit signed integer, reverse digits of an integer. Example 1: Input: 123 Output: 321 Note:Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231,  231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. Required …
