Here is problem solution in Python, Java, C++, C and Javascript - https://programmingoneonone.com/hackerrank-electronics-shop-problem-solution.html

static int getMoneySpent(int[] keyboards, int[] drives, int b) { /* * Write your code here. */ int ans=-1; Arrays.sort(keyboards); Arrays.sort(drives); int i=keyboards.length-1,j=0; int curr=-1; System.out.println(keyboards); System.out.println(drives); while(i>-1 && jb){ i--; }

        else{
            curr=keyboards[i]+drives[j];
             j++;
        }

        if(curr>ans)
        ans=curr;
     }


     return ans;

}

Question details could have been simpler

Here is my c++ solution, you can find the video here : https://youtu.be/yC-TXToDbD0

int getMoneySpent(vector<int> keyboards, vector<int> drives, int b) {
    int ans = -1;
    for(int k : keyboards){
        for(int d : drives){
            if(k + d > ans && k + d <= b) ans = k + d;
        }
    }
    return ans;
}
