最近在学scala语言，scala代码如下：

import scala.collection.JavaConversions._

object Solution {
    def solution(A: Int, B: Int, K: Int): Int = {
        // write your code in Scala 2.10
        var cnt: Int = 0
        // let start element to be zero
        if(A%K != 0) cnt -= K-A%K
        // let end element to be zero too
        if(B%K != 0) cnt -= B%K
        
        cnt +=  B-A+1
        if(cnt <= 0) 0
        else cnt/K+cnt%K
    }
}
