Dada dos veces en formato de string “HH:MM”. Aquí ‘H’ muestra las horas y ‘M’ muestra los minutos. Tienes que encontrar la diferencia en el mismo formato de string entre estas dos strings. Pero ambas strings dadas deben seguir estos casos.
1) El tiempo 1 será menor o igual que el tiempo
2 2) Las horas serán posibles de 0 a 23.
3) Los minutos serán posibles de 0 a 59
Ejemplos:
Input : s1 = "14:00";
s2 = "16:45";
Output : result = "2:45"
Input : s1 = "1:04"
s2 = "13:05"
Output : result = "12:01"
La idea es primero quitar el colon. Después de eliminar los dos puntos, la diferencia horaria se puede calcular usando matemáticas simples.

return stoi(s);

// convert answer again in string with ':'
