The for loop has to go upto word.length/2
I am assuming this code is in C language from the looks of the syntax used.
so, it should be
for (int i = 0; i < word.length/2; i++)
not in touch with C language for a very long time, so I think that word.length is also incorrect.
there has to be a function to get the length of a null-terminated string of C. it should be
strlen(word) and not word.length
Also the return type for the function is missing.
Curious to know the programming language of the code.

Yes! You nailed it :)

We currently run into 2 out of bound exceptions

  1. The initial for loop will break since it goes i < word.length instead of i < word.length - 1. And like you mentioned, an even better solution in this case is i < word.length / 2 since we can confirm its a palindrome after iterating halfway through the array
  2. We also need to address the comparison line. So it would be if (word[i] !== word[word.length - 1 - i])

And its just some Pseudocode! Its not an actual language (although I based it off a mixture of C and Python :) )

Thanks
There won't be out of bounds since the condition is i < word.length and not i <= word.length
it's not just a mix of C and python.
e.g. the function is a keyword from languages like PASCAL and Ada, not used in either C or Python.
but, yes I get the point, it is just a pseudo code.

Oh you're totally right! That initial for loop won't have an out of bounds. Good catch :)

The if statement still will though when it iterates the first index since it'll be word[word.length - 0] which will crash
