To repeat a string n number of times, we can use the built-in
String() initializer syntax by passing two arguments. The first argument is which string you need to repeat and the second argument is the number of times you need to repeat that string.
Here is an example that repeats the string
ok for 4 times:
let str = "ok" let repeatStr = String(repeating: str, count: 4) print(repeatStr)
