Bouncy Numbers
CodeChefOpen on judge ↗
In a non-negative integer working from left-to-right if no digit is exceeded by the digit to its left it is called an increasing number; for example, 134468. Similarly if no digit is exceeded by the digit to its right it is called a decreasing number; for example, 66420. We shall call a non-negative integer that is neither increasing nor decreasing a "bouncy" number; for example, 155349. Clearl
