How to print Diamond Pattern in TypeScript ?

Answer

To print a Diamond Pattern in TypeScript, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.

✐ Examples

1 Diamond Pattern

In this example,

We define a function printDiamond that takes the desired number of rows n as a parameter.
We use two nested for loops, where the outer loop runs from 1 to n and the inner loops control the spaces and stars in each row.
Within the inner loops, we calculate the number of spaces and stars based on the current row number to form the diamond pattern.

TypeScript Program

function printDiamond(n: number): void {
    for (let i = 1; i <= n; i++) {
        let spaces = ' '.repeat(n - i);
        let stars = '*'.repeat(2 * i - 1);
        console.log(spaces + stars);
    }
    for (let i = n - 1; i >= 1; i--) {
        let spaces = ' '.repeat(n - i);
        let stars = '*'.repeat(2 * i - 1);
        console.log(spaces + stars);
    }
}

// Example usage
printDiamond(5);
