Given a array arr of integers, return the sums of all subsets in the list. Return the sums in any order. Here’s…

Given a collection of candidate numbers (candidates) and a target number (target), find all unique combinations in candidates where the candidate numbers…

Given an array of distinct integers candidates and a target integer target, return a list of all unique combinations of candidates where the chosen numbers sum to target. You may return the…

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses. Here’s the [Problem Link] to begin with. Example…

Given an integer N , Print all binary strings of size N which do not contain consecutive 1s. A binary string is that string…

Given an array arr of non-negative integers and an integer target, the task is to count all subsets of the array whose sum…

Hey students! If you’re exploring recursion and backtracking, this problem is a great follow-up to subsets or subsequences. It’s like the “Subsets with Sum K” but simpler,…

Given an array of positive integers and a target sum K, generate and print all subsequences of the array whose sum equals K. A subsequence is a sequence that…

Hey students! If you’re diving into recursion and backtracking, the “Subsets” problem (also known as generating the power set or all subsequences) is a perfect starting point. It’s like deciding…

You are given two integers L and R, your task is to find the XOR of elements of the range…
