# Print all funny words in a string

We are given a sentence. Our task is to print all funny words/strings in that sentence.

#### What is a funny word ?

Reverse the given string. Iterate through each character of that string, compare the absolute difference in the ASCII values of the characters at positions 0 and 1, 1 and 2, 2 and 3 and so on to the end. If the list of absolute differences is the same for both strings, they are funny otherwise not.
Examples:

```Input  : HKMNPS
Output : Yes
Let r be the reverse of original string s
s = "HKMNPS"
r = "SPNMKH"
|H-K| = 3  = |S-P|
|K-M| = 2  = |P-N|
|M-N| = 1  = |N-M|
|N-P| = 2  = |M-K|
|P-S| = 3  = |K-H|
Since each comparison is equal so given string is funny

Input  : bdwy
Output : No
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

NOTE : Every palindrome string is a funny string but not vice-versa.

The idea is to split string into words. For every word, traverse it from both ends and compare differences between adjacent characters.
