Microsoft Internship interview questions

It was good. The interviewer was friendly and he gave me hints whenever I was stuck at any point during the interview. I didn't got through, but had a good experience

motorq intern#include <iostream> #include<bits/stdc++.h> using namespace std; int main() { int sum = 0; int num; cin >> num; //Reading input from STDIN // cout << "Input number is " << num << endl; // Writing output to STDOUT int n,m; cin>>m>>n; int cost[m][n]; for(int i = 0; i<m; i++) { for(int j = 0; j<n; j++) { cin>>cost[i][j]; } cout<<"\n"; } vector<int> bought(n,0); for(int i = 0; i<m; i++) { vector<int> temp(n); copy(cost, cost+n, temp); sort(cost, cost+n, greater<int>()); int index = find(temp.begin(), temp.end(), cost[i][0]); if(bought[index] == 1) { temp[index] = 0; for(int j = 0; j<n; j++) { if(j!=index) { sum += temp[j]; bought[j] = 1 } } } else { index = find(temp.begin(), temp.end(), cost[i][1]); temp[index] = 0; for(int j = 0; j<n; j++) { if(j!=index) { sum += temp[j]; bought[j] = 1 } } } } cout<<sum; }
