Given a positive number **X**. Find the largest Jumping Number smaller than or equal to X.

**Jumping Number: **A number is called Jumping Number if all adjacent digits in it differ by only 1. All single digit numbers are considered as Jumping Numbers. For example **7**, **8987** and **4343456** are Jumping numbers but **796** and **89098** are not.

**Example 1:**

Input:X =10Output:10Explanation:10 is the largest Jumping Number possible for X = 10.

**Example 2:**

Input:X =50Output:45Explanation:45 is the largest Jumping Number possible for X = 50.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **jumpingNums()** which takes an Integer X as input and returns the largest Jumping Number less than or equal to X.

**Expected Time Complexity:** O(k), where k is no of jumping numbers

**Expected Auxiliary Space:** O(k), where k is no of jumping numbers

**Constraints:**

1 <= X <= 10^{9}
