Question

How to write a recursive function that divides two numbers in Swift

Answer 1

import Foundation

func divide(_ dividend: Int, _ divisor: Int) -> Int {
    // Handle division by zero
    guard divisor != 0 else {
        fatalError("Division by zero is not allowed")
    }

    // Base case: If the dividend is less than the divisor, return 0
    if dividend < divisor {
        return 0
    }

    // Recursive case: Subtract divisor from dividend and add 1 to the result
    return 1 + divide(dividend - divisor, divisor)
}

let dividend = 28
let divisor = 4

let result = divide(dividend, divisor)
print("Result of dividing \(dividend) by \(divisor) is: \(result)")



/*
run:

Result of dividing 28 by 4 is: 7

*/
