Given two positive integers num1 and num2, the task is to find the product of the two numbers on a 12-hour clock rather than a number line.
Note: Assume the Clock starts from 0 hours to 11 hours.
Examples:
Input: Num1 = 3, Num2 = 7
Output: 9
Explanation: 3*7 = 21. The time in a 12 hour clock is 9.Input: Num1 = 3, Num2 = 4
Output: 0
Approach: Follow the steps to solve this problem:
- Calculate Product as Num1*Num2 and store it in a variable Prod.
- If Prod = 12, return 0.
- Else If Prod ? 0 and Prod ? 11, return Prod.
- Else return, Prod % 12.
Note: You can skip all the steps and return (Num1*Num2) % 12 also, it also works fine.
Below is the implementation of the above approach.
C++
// C++ code to implement the approach#include <bits/stdc++.h>using namespace std;// Function to find the product of// the two numbers on a 12-hour clockint multiClock(int Num1, int Num2){ return (Num1 * Num2) % 12;}// Driver Codeint main(){ int num1 = 3, num2 = 7; // Function Call cout << multiClock(num1, num2) << endl; return 0;} |
Java
// Java code for the above approachimport java.io.*;class GFG{ // Driver Code public static void main (String[] args) { int num1 = 3, num2 = 7; // Function Call System.out.println(multiClock(num1, num2)); return; } // Function to find the product of the two numbers on a 12-hour clock static int multiClock(int Num1, int Num2) { return (Num1 * Num2) % 12; }}// This code is contributed by ajaymakvana. |
Python3
# Python code to implement the approach# Function to find the product of the two numbers on a 12-hour clockdef multiClock(Num1,Num2)->int: return (Num1*Num2) % 12# Driver Codeif __name__ == '__main__': num1 = 3 num2 = 7 # Function Call print(multiClock(num1,num2)) # This code is contributed by ajaymakvana. |
C#
// C# code to implement the approachusing System;class GFG {// Function to find the product of// the two numbers on a 12-hour clockstatic int multiClock(int Num1, int Num2){ return (Num1 * Num2) % 12;} // Driver codepublic static void Main(string[] args){ int num1 = 3, num2 = 7; // Function Call Console.Write(multiClock(num1, num2));}}// This code is contributed by code_hunt. |
Javascript
<script> // JS code to implement the approach function multiClock(Num1, Num2) { return (Num1 * Num2) % 12; } // Driver Code let num1 = 3, num2 = 7; // Function Call document.write(multiClock(num1, num2)); // This code is contributed by Potta Lokesh </script> |
Output
9
Time Complexity: O(1)
Auxiliary Space: O(1)
