In the not so easy maths problem,if I initialise n and ans along with t, I get a wrong answer but if I iniitialise them inside the while(t–),I get a right answer. Why is that?
Declaration of n and answer
@aiman.mumtaz hi,t here refers to test cases so in each test case ans is different according to input of that test case and if you declare ans outside while t- - than it will be global variable so behave as single variable for each test case to usi me changes hote jayenge ,islie hm har test case me nya varisble ans lerhe hai taki ans har test case ke lie alg rhe.
