ohh I was late to read this post…

I have a doubt from your contest in Tricky Eyes

for test case

240 36 you gave null output… that means according to you there is no answer possible…

#while if we keep clock at +36 then…

at 9:12

#angle of minute hand would be (72-36)= 36

and

#angel of hour hand would be (270+(12/2)-36)=240

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

int main() {
int h,m,i,j,a,b;
bool flag=false;
cin >> h >> m; 

for(i=0;i<12;i++){
    for(j=0;j<60;j+=2){
        a=6*j;
        b=(30*i)+j/2;
        if(((a-m)%360+360)%360==((b-h)%360+360)%360){
             flag=true;
             break;
        }
    }
    if(flag)
        break;
}       

  

  if(flag){
    cout << setfill('0') << setw(2) << i ;
    cout << ":";
    cout << setfill('0') << setw(2) << j ; 
  }    
  else 
     cout << "";

  return 0;
 }

Here is a solution passing all of your test cases except 3rd one…
