Shouldn't there be a proper documentation for problem setters ??

Recently I came across this Contest held on Codechef and the problems here are not enough descriptive specially the input ,( one has to judge by himself ) specially problem 3,4 and 5 .

Problem 3
Problem 4
Problem 5

The poor description of these problems has reflected on the total number of AC’s on these problems .

Please @admin @vijju123 have a look at this.
