Choose appropriate data type to store the square of values ranging from 99 to 300 - Java Quiz Question

Correct Answer : C

-99 * -99 = 9801
300 * 300 = 90000
So we need to use an optimal datatype whose range holds both of the above values. Range of int is -2,147,483,648 to 2,147,483,647. So int is suitable size.
byte will not include both the values.
short includes first value but not the second one.
long includes both but using int saves space.
