I am trying to solve Niceness of the string but i am getting WA because i think i am unable to process blank lines. For blank lines output will be zero. I am using scanf(" %[^\n]s",a) which will ignore blank lines.

std::getline()
Thank you! getline will behave weirdly if we don't ignore \n. So i came across this. Putting cin.ignore() after scanf("%d",&T) and using getline() gave AC.
There is no weirdness in getline:
Got it. By adding extra getline before taking string as input we can ignore \n.
Replacing
scanf("%s",a)
withgets(a)
may help. But remember togetchar()
afterscanf("%d",&T)
to skip the '\n' in the first line.Looks like getchar works a bit faster than cin.ignore(). Thanks!
If you want to skip
'\n'
, you can write:scanf("%d\n",&T)
. But this works with bugs when you debug your program (if you are not reading from the file).scanf is for queers
