To print a Diamond Pattern in Swift, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printDiamond
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from 1 to n
and the inner loops control the spaces and stars in each row.func printDiamond(_ n: Int) {
for i in 1...n {
let spaces = String(repeating: " ", count: n - i)
let stars = String(repeating: "*", count: 2 * i - 1)
print(spaces + stars)
}
for i in (1...(n - 1)).reversed() {
let spaces = String(repeating: " ", count: n - i)
let stars = String(repeating: "*", count: 2 * i - 1)
print(spaces + stars)
}
}
// Example usage
printDiamond(5)
