Many people like to solve hard puzzles some of which may lead them to madness.One such puzzle could be finding a hidden prime number in a given text.Such number could be the number of different substrings of a given size that exist in the text.As you soon will discover,you really need the help of a computer and a good algorithm to solve such a puzzle.
Your task is to write a program that given the size,N,of the substring,the number of different characters that may occur in the text,NC,and the text itself,determines the number of different substrings of size N that appear in the text.
As an example,consider N=3,NC=4 and the text daababac.The different substrings of size 3 that can be found in this text are:daa,aab,aba,bab,bac.Therefore,the answer should be 5.
Input
The first line of input consists of two numbers,N and NC,separated by exactly one space.This is followed by the text where the search takes place.You may assume that the maximum number of substrings formed by the possible set of characters does not exceed 16 Millions.
Output
The program should output just an integer corresponding to the number of different substrings of size N found in the given text.
This problem contains multiple test cases!
The first line of a multiple input is an integer N,then a blank line followed by N input blocks.Each input block is in the format indicated in the problem description.There is a blank line between input blocks.
The output format consists of N output blocks.There is a blank line between output blocks.

You are given n closed,integer intervals [ai,bi] and n integers c1,...,cn.
Write a program that:
> reads the number of intervals,their endpoints and integers c1,...,cn from the standard input,
> computes the minimal size of a set Z of integers which has at least ci common elements with interval [ai,bi],for each i = 1,2,...,n,
> writes the answer to the standard output.
Input
The first line of the input contains an integer n (1

许多人想解决难题,其中一些可能会让他们疯狂.一个这样的难题就是找到一个隐藏在给定文本中的质数.这个数字可以是一个存在于这个文本中指定长度的不同子串数.你需要计算机和一个好的算法来帮助你解决这样一个难题.
Your task is to write a program that given the size,N,of the substring,the number of different characters that may occur in the text,NC,and the text itself,determines the number of different substrings of size N that appear in the text.
你的任务是写这样一个程序：给定子串大小N,文本中不同字符的数量NC,和文本,来确定出现在文本中大小为N的不同子串数目.
As an example,consider N=3,NC=4 and the text daababac.The different substrings of size 3 that can be found in this text are:daa,aab,aba,bab,bac.Therefore,the answer should be 5.
比如：假设N为3,NC为4,文本为daababac.这里不同子串大小为3,为daa,aab,aba,bab,bac.因此,答案应该是5.
