You're welcome bruh, glad if it helps : )

Answer 2

The return statement is used by a function to return something to the function caller. Think of functions like robots you can teach to do something, your code for the robot describes what a robot can do, the robot can accept raw materials from you, we call the raw materials "arguments". And it can output something to be given back to you, we call the output "return value".

Imagine you have a robot that can bake, you give it flour, yeast (arguments) and it return to you a bread (return value).

Hope you understand bruh : )

Answer 3

a jagged array is an array of arrays
when you do myArr[0], that points to the first array
when you do myArr[0][2], that points to the third item in the first array
myArr[1][0] points to the first item in the second array

Answer 4

One way to understand multidimensional arrays better is to break them into multiple lines, where each line consists of columns (index) like a spreadsheet;

int[][] myArr = {
Column or index →
Row ↓ 0 1 2
0 {1, 2, 3},
1 {4},
2 {5, 6, 7}
};

Hth, cmiiw
