Print multiples of Unit Digit of Given Number

• Difficulty Level : Basic
• Last Updated : 26 Apr, 2021

Given a number . The task is to print the multiples of the unit digit of N from the unit digit of N to N
Note: If the unit digit is 0 then print the multiples of 10.
Examples:

Input : 39
Output : 9 18 27 36
Explanation : The unit digit of 39 is 9.
So the multiples of 9 between 9 and 39 are:
9, 18, 27, 36

Input : 25
Output : 5 10 15 20 25

Simple Approach

1. Find the unit digit of the input number. Unit digit of N will be (N%10), i.e. remainder upon dividing N by 10.
2. Check if the unit digit is 0.
• If yes then consider the multiple as 10.
3. Print the multiples of unit digit until it is less than or equal to the input number.

Below is the implementation of the above approach:

C++

 // C++ program to print multiples of// Unit Digit of Given Number#include  using namespace std; // Function to print the multiples// of unit digitvoid printMultiples(int n){    // Find the unit digit of    // the given number    int unit_digit = n % 10;     // if the unit digit is 0 then    // change it to 10    if (unit_digit == 0)        unit_digit = 10;     // print the multiples of unit digit    // until the multiple is less than    // or equal to n    for (int i = unit_digit; i <= n; i += unit_digit)        cout << i << " ";} // Driver Codeint main(){    int n = 39;     printMultiples(n);     return 0;}

Java
