How to print Hollow Square Pattern in TypeScript

How to print Hollow Square Pattern in TypeScript ?

Answer

To print a Hollow Square Pattern in TypeScript, you can follow a similar approach to JavaScript using nested loops and conditions to control the printing of stars and spaces.

✐ Examples

1 Print Hollow Square Pattern

In this example,

We define a function named printHollowSquare that takes the side length n as a parameter.
We use two nested for loops, one for rows and one for columns, to iterate through each cell of the square.
Within the loops, we use conditions to check if we are at the border or inside the square, printing stars (*) for the border and spaces ( ) for the inside.
Finally, we call printHollowSquare with the desired side length to print the pattern.

TypeScript Program

function printHollowSquare(n: number): void {
    for (let i = 0; i < n; i++) {
        let row = '';
        for (let j = 0; j < n; j++) {
            if (i === 0 || i === n - 1 || j === 0 || j === n - 1) {
                row += '*';
            } else {
                row += ' ';
            }
        }
        console.log(row);
    }
}

const sideLength: number = 5;
printHollowSquare(sideLength);
