# Extract Digits of a Number

# Problem Statement

1Problem Description :2Given a number, print all digits present in the number34Example 1 :5 Input : n = 1536 Output : 1, 5, 37 Explanation : 1, 5 and 3 are digits present in number 15389Example 2 :10 Input : n = 12111 Output : 1, 2, 112 Explanation : 1, 2 and 1 are digits present in number 121.

# Procedure

To understand the logic, lets consider given number as 153. For given number, we can easily find out the digit present at units place by dividing the number by 10.

Step 1: number = 153

Step 2: when we divide the number by 10, we get remainder as 3 which is the digit at 1’s place and 15 is the quotient after dividing the number by 10.

Step 3: Now we need to get remaining digits other than 3, so we can update number as number/10 (i.e., quotient which we got in step2) and we again divide the number by 10 which will give remainder as 5 and quotient as 1.

Step 4: Now we consider the number as 1 and again we divide the number by 10, we get remainder as 1 and quotient as 0. i.e., so the procedure gets stopped here and we have extracted all digits of the given number.
