Constraint Means the upper and lower limits of Input Data.It also means the Set of Valid Input Data.

1 <= T <= 1000        //Means the value of T in Input Data set  is greater than or equal to 1
                      //and less than or equal to 1000


5 <= A[K] <= 100  //means the value of each member of Array A is greater than or equal to 5
                     //and less than or equal to 100

Code-chef is very serious ,they wont give u the data that is not allowed or that does not satisfy the constraint.Code-chef infact guarantee that there is no test data that does not satisfy the given constraint.

" if user try to input data that is not allowed ask him again for data or it is just to let us see the limits of input"

Well it never gives such data .You don’t have to unnecessarily check and skip every-time while Taking Input.
