How to print Left Half Pyramid Pattern in Swift

How to print Left Half Pyramid Pattern in Swift ?

Answer

To print the Left Half Pyramid Pattern in Swift, we use nested loops where the outer loop controls the rows and the inner loop prints spaces and stars.

✐ Examples

1 Left Half Pyramid Pattern

In this example,

We define the size of the pyramid, n, which is set to 5 in this example.
We use two nested loops: an outer loop to handle rows and an inner loop to print spaces and stars.
The outer loop runs from 1 to n, controlling the number of rows.
The inner loop in Swift prints spaces based on the difference between n and the current row, followed by stars equal to the current row number.
This combination of loops and print statements creates the Left Half Pyramid Pattern.

Swift Program

func printLeftHalfPyramid() {
    let n = 5
    for i in 1...n {
        let spaces = String(repeating: " ", count: n - i)
        let stars = String(repeating: "*", count: i)
        print(spaces + stars)
    }
}

printLeftHalfPyramid()

Output
