How to approach this problem?

#1

i couldn’t find a way to do it without ascii… any hints would be helpful

#2

You can do by conditional statements like
if(ch>=‘A’&&ch<=‘Z’) uppercase
else if(ch>=‘a’&&ch<=‘z’) lowercase

#3

ohh i did the same… but at the end we are comparing the characters and it is known that internally there is comparison of ascii values only

#4

Yeah…internally ascii are still being compared. But still…there is no more alternative…
Here you were supposed to do just as i said

#5

ok bhaiiya thankyou :slight_smile:
