how to apply constraints to variable as said in the questions? Otherwise, when I ran my code CodeChef does not give any points to complete subtask.
The input files of the problems already satisfy all of the given constraints . You don’t need to check for any constraints . They are there for your understanding of the input .
Constraints are given for your understanding, to develop a code suitable for given constraints…
For example, code to find factorial upto n <= 10 can be done using int data type,
but for n <= 100, You have to go for large datatype… (BigInteger in java)
Another use of constraints is to analyse time complexity…
You can analyse your code’s time complexity using constraints using Big-O notation using following links
