Prerequisites : Find angle between minute & hour hand  

Basically in this question we have to print minimum angle. Our approach will be similar to above question. 

1) By using sub string function we will extract hour & minute.

2) Then we will change it to numerical form

3) Convert time in 12 hour format

4) Finally apply logic & display the result 

#include<bits/stdc++.h>
using namespace std;

#define rep(a,b) for(ll ii=a;ii<b;ii++)
#define ll long long int
#define test() int tt; cin>>tt; while(tt--) 
#define fst_io ios_base::sync_with_stdio(false);cin.tie(NULL);
#define endl '\n'

int main()
{
  string s, s1, s2;	
  int n1, n2;
  float h;
  test()
  {
    cin>>s;
    s1 = s.substr(0, 2);
    n1 = (int)(s1[0] - '0') * 10 + (int)(s1[1] - '0');

    s2 = s.substr(3);
    n2 = (int)(s2[0] - '0') * 10 + (int)(s2[1] - '0');

    if(n1>12) n1 -= 12;
    
    h = (n1 * 60 + n2) * 0.5;
    n2 = n2 * 6;
    cout<<min(abs(h-n2), 360-abs(h-n2))<<" degree"<<endl;
  }
  return 0;
}
