A Pythagorean Triplets is a set of three integers a, b, c such that a2+b2=C2. In the given limit L. Find the number of Pythagorean Triplets R that can be formed (such that a<b<c).
Create a class called time that has separate int member data for hours, minutes, and
seconds. One constructor should initialize this data to 0, and another should initialize it
to fixed values. Another member function should display it, in 11:59:59 format. The final
member function should add two objects of type time passed as arguments. A main() program should create two initialized time objects (should they be const?) and one that isn’t initialized. Then it should add the two initialized values together, leaving the result in the third time variable. Finally it should display the value of this third variable. Make appropriate member functions const.
Implement your own version of the priority queue data structure using java with OOPs principles mentioned functionalities: enqueue, Dequeue (highest priority), peek(highest priority), contains, size, center, sort reverse, iterator, traverse/print.
Use of similar data structures already present in the language/framework is not allowed.

Area and Perimeter of square
you are given a side of square as input.Write a program to find the perimeter and area of square.
input
the input is an integer representing the length of the side of the square
output
the first line of the output should contain area of the square, and the second line of the output should contain the perimeter of the square as per the format shown in the sample output.
explanation
given the length of the side is 2 .
as the area of square is side*side and perimeter of the square is 4*side
the output should be
area of the square is : 4
perimeter of the square is : 8
sample input 1
3
sample output 1
area of the square is : 9
perimeter of the square is : 12
sample input 2
4
sample output 2
area of the square is : 16
perimeter of the square is : 16
