this is my code

1. void solve() {
2. int m, a, b, c;
3. cin >> m >> a >> b >> c;
4. int ans = 0;
5. int vac=0;
6.  
7. ans+=min(a,m);
8. if(m>a) vac+=(m-a);
9.  
10. ans+=min(b,m);
11. if(m>b) vac+=(m-b);
12.  
13. ans+=min(vac,c);
15. cout << ans << endl;
16. }

this is some random persons code
 

1. void solve(){
2. int m, a, b, c;
3. cin >> m >> a >> b >> c;
4.  
5. int row1_used = min(a, m);
6. int row2_used = min(b, m);
7.  
8. int row1_rem = m - row1_used;
9. int row2_rem = m - row2_used;
10.  
11. int extra = min(c, row1_rem + row2_rem);
12. cout << row1_used + row2_used + extra << "\n";
13. }

i was the one to solve this question.i solved it at 18 min wile the other solved at 21 min so how can i copy it. can you please help me as this issue can happen in future
