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

Answer 1

fun integerIncludeDigitXTimes(n: Int, xtims: Int, digit: Int): Boolean {
    var number = n
    var count = 0

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

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

fun main() {
    println(integerIncludeDigitXTimes(7097175, 3, 7))
    println(integerIncludeDigitXTimes(70975, 3, 7)) 
}
