题目描述
Little Leticija is preparing for a programming exam. Even though she has solved a lot of tasks, there’s one still left unsolved, so she is asking you for help. You are given the word S and Q queries. In each query, you are given positive integers A, B, C and D. Let’s say that word X consists of letters between positions A and B in word S, and word Y from letters between positions C and D in word S. For each query, you must answer if it is possible to somehow rearrange the letters in word Y and obtain word X.

输入格式
The first line of input contains the word S (1 ≤ |S| ≤ 50 000). |S| denotes the number of characters in word S, which consists of lowercase letters of the English alphabet. The second line of input contains the positive integer Q (1 ≤ Q ≤ 50 000).

Each of the following Q lines contains four integers A, B, C i D (1 ≤ A ≤ B ≤ |S| and 1 ≤ C ≤ D ≤ |S| ) from the task.

输出格式
For each query, output “DA” (Croatian for yes) if it is possible, and “NE” (Croatian for no) if it is not.

题目描述

Little Leticija正在准备编程考试。虽然她已经解决了很多任务，但还有一个任务尚未解决，所以她正在向你寻求帮助。您将获得单词S和Q查询。在每个查询中，给出正整数A，B，C和D.假设单词X由单词S中位置A和B之间的字母组成，而单词S中位置C和D之间的字母组成单词Y.如果可以以某种方式重新排列单词Y中的字母并获得单词X，则必须回答。

输入输出格式

输入格式： 第一行输入包含单词S（1≤| S |≤50000）。| S | 表示单词S中的字符数，由英文字母的小写字母组成。第二行输入包含正整数Q（1≤Q≤50000）。 以下Q行中的每一行包含来自任务的四个整数A，B，C i D（1≤A≤B≤| S |且1≤C≤D≤| S |）。 输出格式： 对于每个查询，如果可能，输出“DA”（克罗地亚语为yes），如果不可能，则输出“NE”（克罗地亚语为否）。

提示

In test cases worth 50% of total points, it will hold: 1 ≤ |S| ≤ 1000 and 1 ≤ Q ≤ 1000.

Clarification​ ​of​ ​the​ ​third​ ​test​ ​case:

In the first query, X=”vovo”, and Y=”devo”. In the second query, X=”odev”, and Y=”devo”.
