Trimorphic Number.cpp

/*
This program check if the user input is a Trimorphic number or not.
Also print the Trimorphic Number Upto Given Input number.

A Trimorphic number is a number whose cube ends in the number itself.

For example:
Input: 4
Output: true (4^3 is 64, which ends in 4)

Input: 24
Output: true (24^3 = 13824)

Input: 249
Output: true (249^3 = 15438249)
