Code Challenge : Palindrome Checker
Let’s try a simple coding challenge of checking palindromes in python.
A palindrome is a type of string that returns the same value if read from both sides.
Palindrome string can also have spaces in them but they are ignored, for example:
“never a foot too far even” is a palindrome.
So how do we write it.
The simplest way is to just reverse the string and compare, but here is another way to do it.
Create two pointer variables, start and end. Set start to 0 and end to length of string minus 1
Create a while loop that runs until start is less than end.
Within the loop if character at start position is space, we ignore it and increment start.
If character at end position is space, we ignore it and increment end.
If character at start and end are not same, we return false as the string cannot be palindrome now.
If none of these conditions match, just increment start and end.
If the code runs through the while loop successfully, return true
