Constraint doubt

is it necessary to write constraints in every problem like N>0 andN<100000000 .or how could we make sure that code dont run out of the following constraint.

hello @lovely

yeah constraints are necessary ,this given us idea about expected time complexity ,space complxity

checker will run ur code without violating any mentioned constraint ( u dont have to anything for it ,it will be taken care).

so u mean we dont have to mention the constraints but write code according to it?

yeah…(why u will mention? it will be already mentioned in problems)
