finding the missing alphabet in a palindrome series.in the below code i could not understand the looping condition .can any one

Question

inputstr = input().strip()
fwdindex = 0
revindex = len(inputstr)-1
while(fwdindex != revindex):
if inputstr[fwdindex] != inputstr[revindex]:
if inputstr[fwdindex] == inputstr[revindex-1] and fwdindex != revindex-1:
print (inputstr[revindex])
else:
print (inputstr[fwdindex])
break
fwdindex+=1
revindex-=1

Answer 1

it seems like, its homework
wow, if that so, then your code is too complicated
im too kind today, so i will give u the code

now look, even now i give you the code, dont lazy. your question is good, but not clear. next, if you want to ask question again, dont ask them the code. ask the hint :v
but like i said before, im too kind today. so, happy coding :v

Answer 2

this code is about that in a palindrome series for eg."malayalam"
if the input is like"malayala" then i have to find the the missing character in the palindrome which is "m" in this case.here in this code i could not understand the outer looping conditions
