A tech number has even number of digits. If the number is split in two equal halves, then the square of sum of these halves is equal to the number itself. Write a program to generate and print all four-digit tech numbers.
Example :
Consider the number 3025
Square of sum of the halves of 3025 = (30+25)2
= (55)2
= 3025 is a tech number.

Design a class to overload a function Joystring( )as follows:
(i) void Joystring (String s, char ch1 char ch2) with one string argument and two character arguments that replaces the character argument ch1 with the character argument ch2 in the given string s and prints the new string.
Example:
Input value of s = “TECHNALAGY”
ch1=‘A’,
ch2=‘O’
Output: TECHNOLOGY
(ii) void Joystring (String s) with one string argument that prints the position of the first space and the last space of the given string s.
