* ** *** **** *****

Solution

n = 5
for i in range(1, n + 1):
    print("*" * i)

const n = 5;
for (let i = 1; i <= n; i++) {
  console.log("*".repeat(i));
}

public class Main {
    public static void main(String[] args) {
        int n = 5;
        for (int i = 1; i <= n; i++) {
            StringBuilder row = new StringBuilder();
            for (int j = 0; j < i; j++) row.append("*");
            System.out.println(row.toString());
        }
    }
}

fun main() {
    val n = 5
    for (i in 1..n) {
        println("*".repeat(i))
    }
}

let n = 5
for i in 1...n {
    print(String(repeating: "*", count: i))
}

void main() {
  int n = 5;
  for (int i = 1; i <= n; i++) {
    print('*' * i);
  }
}
