Question

# Check whether the number is Bouncy number or not using only main method.

**Bouncy number is one in which a non-negative integer is neither an increasing number nor a decreasing number.**

**An increasing number is a non-negative integer in which the digits from left to right are arranged in such a way that no digit on the left is greater than the digit to its right. For example, 1223 **

**A decreasing number is a non-negative integer in which the digits from left to right are arranged in such a way that no digit on the left is smaller than the digit to its right. For example , 3221**

```Enter the number
1231
1231 is a Bouncy Number
Here 1231 is neither increasing number nor decreasing number so it is a bouncy number.
