[Question]: Find maximum sum of a subarray of size k example [9,1,3,2,6,1,5,9], k: 4 = output: 21 (6+1+5+9)Solution: with sliding window we can achieve. first we take sum of first k elements further move elements by 1 window size & add the latest var & remove last var.

[Question]: – Add two numbers using the ListList in swift. Ex Input: l1 = [2,4,3], l2 = [5,6,4] Output: [7,0,8] Explanation: 342 + 465 = 807. Explanation: # Recursion Approach: Create a sum variable & add two nodes with a previous reminder on the recursive call use modulo operator to use the numerator value (7%10

[Question]: Given an integer array that may contain duplicates, find all possible subsets (the power set). No duplicates allowed in answer. Solution in any order allowed. Input: nums = [1,2,3] Output: [1,2,3] [1,2] [1,3] [1] [2,3] [2] [3] [] Approach #2: Using Bitwise OperatorQuestion: Power Set: Print all the possible subsequences of the String To check
