61) Write a program to input a number and
check whether it is Tech Number or
not? (3025= (30+25)2 = (55)2 =3025 so it is tech number).
import java.util.*;public class Tech_number{public static void main(String args[ ]){Scanner sc = new Scanner (System.in);System.out.println("Enter a number");int a = sc.nextInt();int k = a;int c = 0;while(k>0){k=k/10;c++;}if(c%2==0){int x = (int)Math.pow(10,(c/2));int m = a%x;int n = a/x;int y = (int)Math.pow((m+n),2);if(y==a){System.out.println("Entered number is a TECH Number");}else{System.out.println("Entered number is not a TECH Number");}}else{System.out.println("Entered number is not a TECH Number");}}}
