You are given an array of n elements and a sum value, you have to calculate the total number of ways to calculate the given sum using the elements of the array by using only addition(+) and subtraction operator(-).

Value of n should lie between [1,15]

array => [-1, 9, 8, -3, 4] value sum => 5

Output -: 8

I have applied Recursion and Memo also but I want a space Optimization Approach for this Question. Please Explain the Working and Time Complexity of this Code and share the Code snippet.

Hi I was wondering how to solve this question. The question actually came today in the weekly contest. The Question Name is -: 2952. Minimum Number of Coins to be Added . And my general approach was to just try recursion here and use pick and not pick approach to find out the element from 1 to Target. It's giving me wrong answer in the Tc -: [1,4,10] Target -: 19. My answer is 3 while the correct answer is 2. Can we try this approach to find out the answer. I know it will give the TLE but just for the practice purpose I want to try recursion here.

Hi I was wondering why can't we use recursive Solution for Coin Piles Solution. This is the Problem

I have tried recursive solution but end up getting TLE and Runtime Error. Can anyone explain whether we can use Recursion or Dynamic Programing. This is my Solution.

This is my Soluion
