fun longestConsecutiveZeroes(n: Int): Int {
    // Function to find the longest sequence of consecutive zeroes in binary representation
    var maxCount = 0
    var currentCount = 0
    var num = n

    while (num > 0) {
        if ((num and 1) == 0) { // Check if the least significant bit is 0
            currentCount++
            maxCount = maxOf(maxCount, currentCount) // Update maxCount
        } else {
            currentCount = 0 // Reset count when a 1 is encountered
        }

        num = num shr 1 // Right shift the number
    }

    return maxCount
}

fun main() {
    val num = 11298 // Binary: 0010110000100010
    
    println("Longest consecutive zeroes: ${longestConsecutiveZeroes(num)}")
}



/*
run:

Longest consecutive zeroes: 4

*/
