Program

import java.util.*; public class x { public static void main(String args[]) { Scanner sc = new Scanner(System.in); long n = sc.nextLong(); long k = sc.nextLong(); long i=0,r=0; for(i=0;i<k;i++) { r=n%10; if(r!=0) { n = n-1; } else if(r==0) { n= n/10; } } System.out.println(n); } }

Output

I/P : ------ 512 4 ------ O/P : ------ 50
