N Integers – Sum S – All Combinations(Weekly Test)

-
A number S is passed as input. Also N positive unique integers are passed as input to the program. One or more numbers (out of these N integers) can be added to form the number S. Several such combinations are possible and the program must print the count C of such combinations. You need to optimize the code so that it executes within the given time (failing which Time exceeded Error will be obtained). Input Format: The first line will contain S and N separated by a space. The second line will contain the value of N positive integers, with the values separated by a space. Output Format: The first line will contain the the count C Boundary Conditions: 1 <= S <= 99999 2 <= N <= 50 Example Input/Output 1: Input: 10 5 1 2 3 4 5 Output: 3 Explanation: The three combinations which add up to 10 are 1 4 5 2 3 5 1 2 3 4  Code: #include<stdio.h> #include<string.h> short int subset[999][999],cnt=0; void print(int a[...
