WHY WA#4????

#include<stdio.h>
#include<math.h>
void main(){
int v=0,m,n;
scanf("%d",&n);
int* a=new int[n];
int* b=new int[n];
int* c=new int[n];
scanf("%d",&m);

for (int i=1;i<=n;i++){
scanf("%d",&a[i]);
}

 if(m+11<=n){
        for(int j=m+1;j<=11+v;j++){
                 b[j]=a[j];}

         for(int j=m+1;j<=11+v;j++){
                 printf("%d",b[j]);  }
         }
         else {
         v=m;
         while(v>n){
        v=abs(v-n); }
          for(int i=v+1;i<=n;i++){
                 b[i]=a[i];}
          for(int k=1;k<=10-(n-v);k++){
                 c[k]=a[k];}

          for(int i=v+1;i<=n;i++){
                 printf("%d",b[i]);  }

          for(int k=1;k<=10-(n-v);k++){
                  printf("%d",c[k]);  }
                     }
                 }

Your program always must output 10 digits. Try this test:
15 16
1
2
3
4
5
6
7
8
9
0
1
2
3
4
5
