It does not affect the rules and regulations of codechef, if I ask for input and output explanation. Am I right? So please help me understanding the output for the above problem.
People, please help ! Thanks in advance !
everyone taking part gets equal help 
it takes some time to understand the question .
everyone has to go through that phase before we start to code it . Good Luck
