It seems like an easy problem. But somehow, I am getting a WA. I can’t seem to figure out why. Please have a look
A description of my algorithm - Made two arrays A[26] and a[26] for storing the count of upper case and lower case alphabets, respectively. Then traversed through the arrays, adding to the result the sum of element mod 2 and of element/2.
The problem was that u were separating each line with ‘\n’, but the last line in the test file does not have a ‘\n’. This is what caused WA.
Used scanf() instead and that resulted in AC

Okay, thanks a lot!
@dhruvmullick pls display your gratitude by voting up the answer and accepting it. and your question gonna be closed.
@squal
is there some way to still use fgets() ? Because had this been a string with two words, I wouldn’t have been able to scanf()
@dhruvmullick: u can still do it using scanf scanf(" %[^\n]s",string); CodeChef: Practical coding for everyone (its usage) it inputs a string until a user enters a new line character.
