I ma unable to figure out this question

#1

can you please help get a hint as I am unable to convert my thoughts in code

#2

take two variables size and sum
set intially both to zero

now process elements using recursion

// base case:
if(sum==0&&size>0) return true;

if(i==n)return false;

case 1: consider the element into subset
return rec(arr,i+1,sum+arr[i],size+1);

case 2: doesn’t consider the element
return rec (arr,i+1,sum,size)

this is basic structure of recursive function

i hope this helps

#3

#4
#5

if(inp[i]==’\0’){
out[j]=’\0’;
