How to square an array?

Question

I am to make a code that squares the inputted integer.
The rules is that:
1. The input consist of only one integer
2. The array element should only contain 5 values
3. The output should result with 3 integer places

Ex.1
Input:
1
Output
001
004
009
016
025

Ex2:
Input:
8
Output:
064
081
100
121
144

Answer 1

remove the "int" in first for loop coz it is unnecessary, int keyword is only used to declare an integer. In your case, you already declared num, so no need of that "int".

About that 3 integer places, you can convert Integer to String and format it to add 2 or 1 zero before the answer.
