How to check if an integer include specific digits x times in Swift

Answer 1

import Foundation

func integerIncludeDigitXTimes(_ n: Int, _ xtims: Int, _ digit: Int) -> Bool {
    var number = n
    var count = 0

    // Count occurrences of the digit in the number
    while number > 0 {
        if number % 10 == digit {
            count += 1
        }
        number /= 10 // Perform integer division
    }

    // Return true if count matches xtims
    return count == xtims
}

print(integerIncludeDigitXTimes(7097175, 3, 7)) 
print(integerIncludeDigitXTimes(70975, 3, 7))
