C :

#include <stdio.h>
#include <string.h>
int main()
{
	int i,n,m,j;
	char a[110],b[110];
	scanf("%d%d",&n,&m);
	getchar();
	gets(a);
	for(i=m-1,j=0;i<n;i++,j++)
		b[j]=a[i];
	b[j]='\0';
	printf("%s\n",b);
	return 0;
}

C++ :

#include <stdio.h>
#include <string.h>
int main() {
	char str[101], newstr[101];
	int n, m, i;
	scanf("%d %d", &n, &m);
	scanf("%s", str);
	for (i = m - 1;i < n;i++)
		newstr[i - (m - 1)] = str[i];
	newstr[n - m + 1] = '\0';
	printf("%s\n", newstr);
	return 0;
}

Pascal :

Program TK1288;
var n,m:longint; s:string;

Begin 
	readln(n,m); readln(s);
	writeln(copy(s,m,n-m+1));
End.

Java :

import java.util.Scanner;

public class Main {
   private static Scanner s = new Scanner(System.in) ;
   
   public static void main(String[] args) {
	  int n = s.nextInt() ;
	  int m = s.nextInt() ;
	  
	     String str = s.next() ;
	     System.out.println(str.substring(m-1));
	  }
	  
   }
