Problem Description:

According to the general idea of y, complex multiple judgment statements are avoided by converting it into minute calculation.

First declare that the maximum time does not exceed 24h

Just consider two cases: for example, the start time is (7:20) and the end time is (8:30)

The start time is equivalent to 7*60+20=(th) 440 minutes, and the end time is equivalent to 8*60+30=(th) 510 minutes

After 510-440=70 minutes, 1 hour 10min

However, the elapsed minutes must be greater than 0, provided that the h of the end time is greater than the h of the start time

If the start time is (7:20), then if the end time is in the range of (7:20) to (24:00), it can be calculated like this.

But if the end time falls from (0:00) to (7:20) then it means that the start time passes 24:00 from (7:20), and then reaches the end time from 0:00, so the real elapsed minutes

is (24*60-the number of minutes corresponding to starttime) + the number of minutes corresponding to endtime

To sum up: Elapsed time = endtime-starttime (corresponding minutes) if endtime-starttime>=0

Elapsed time=1440-starttime+endtime (corresponding minutes) if endtiime-starttime<0

C++

#include <cstdio>
#include <iostream>

using namespace std;

int main(){
    int a,b,c,d,starttime,endtime;
    cin>>a>>b>>c>>d;
    starttime=a*60+b;
    endtime=c*60+d;
    if (starttime<endtime) cout<<"O JOGO DUROU "<<(endtime-starttime)/60<<" HORA(S) E "<<(endtime-starttime)%60<<" MINUTO(S)";
    else cout<<"O JOGO DUROU "<<(1440+endtime-starttime)/60<<" HORA(S) E "<<(1440+endtime-starttime)%60<<" MINUTO(S)";
    
    
}

Python: Xiaozheng solves it in three lines (it is not recommended to write this way, it is unnecessary to highlight short and short, it is not easy to understand)

a,b,c,d=map(int,input().strip().split())

start,end=a*60+b,c*60+d

print("O JOGO DUROU %d HORA(S) E %d MINUTO(S)"%((end-start)/60,(end-start)%60)) if start<end else print("O JOGO DUROU %d HORA(S) E %d MINUTO(S)"%((1440+end-start)/60,(end-start)%60))

Recommended writing method: write clearly step by step is good code

a,b,c,d=map(int,input().strip().split())

start=a*60+b
end=c*60+d

if start<end:
    print("O JOGO DUROU %d HORA(S) E %d MINUTO(S)"%((end-start)/60,(end-start)%60)) 
else:
    print("O JOGO DUROU %d HORA(S) E %d MINUTO(S)"%((1440+end-start)/60,(end-start)%60))

I'm Xiao Zheng, and I'm rushing to love and rush to the mountains and seas!
