1. Write a Complete program to compute the area and perimeter of a triangle with three sides: x, y, z

Get user inputs for x, y, z first, and check if the following condition is true or not,

x + y > z and z + y > x and x + z > y

if the condition is not true, ask the user to enter the value of x, y, z again.

The formula for perimeter (p) and area (a) is as below

p = x + y + z

Then compute s = p/2

Area, a = s(s-x)(s-y)(s-z)

Display the values of p, s, a with proper title.
