Answer 2

Hello QTWizard Could you explain which test case might be failed for my code.

Answer 3

Voleti Varshith Well, i think you need to check if there any type of repeated punctuations like:
,Hellomadam,
This will return
,11
i don't understand what your formula abs(...) trying to compute. Anyway, your code works fine, but i think you need to eliminate any type of punctuations.
I have updated my code to print only the longest distance between alphabetical chars.
so the previous case will return
m4 and not ,11

Answer 4

Actually it was asked in a test.The test was completed so I just want to know which test cases failed for my code.

Answer 5

The code inside the abs function finds the last occurring letter in a string and subtracts the first occurring element .This could be write without using abs function also.

Answer 6

According to my logic, the following solution should work on all cases you can think of.
