Question

JAVA Дано число n. С начала суток прошло n минут. Определите, сколько часов и минут будут показывать электронные часы в этот момент. Программа должна вывести два числа: количество часов (от 0 до 23) и количество минут (от 0 до 59). Учтите, что число n может быть больше, чем количество минут в сутках.

public class getTime {

} else if(n > 1440) {
n = n - ((n/1440)*1440);
System.out.print(String.format("Прошло %d часиков и %d минут",n/60,n%60));
} else {
System.out.print(String.format("Прошло %d часиков и %d минут",n/60,n%60));
}

}
}

Answer 2

Problem Analysis

The problem requires determining the number of hours and minutes displayed on electronic clocks given the number of minutes that have passed since the start of the day. The program should output two numbers: the number of hours (ranging from 0 to 23) and the number of minutes (ranging from 0 to 59). It is important to note that the given number of minutes can be greater than the total number of minutes in a day.

Plan

To solve this problem, we can use integer division and modulo operations to calculate the number of hours and minutes. Here is a step-by-step plan: 1. Read the input number of minutes. 2. Calculate the number of hours by performing integer division of the input by 60 (since there are 60 minutes in an hour). 3. Calculate the number of minutes by taking the modulo of the input by 60. 4. Output the calculated number of hours and minutes.

Pseudocode

``` 1. Read n (the number of minutes) 2. hours = n // 60 3. minutes = n % 60 4. Output hours and minutes ```

Implementation

Here is the implementation of the plan in Java:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();
        int hours = n / 60;
        int minutes = n % 60;
        System.out.println(hours + " " + minutes);
    }
}

Example

Let's say the input is `150`. The program will calculate the number of hours and minutes as follows: - `hours = 150 // 60 = 2` - `minutes = 150 % 60 = 30` So the output will be `2 30`, indicating that the electronic clock will display 2 hours and 30 minutes.

Conclusion

In this problem, we used integer division and modulo operations to calculate the number of hours and minutes displayed on electronic clocks given the number of minutes that have passed since the start of the day. The program takes the input number of minutes, performs the necessary calculations, and outputs the number of hours and minutes.
