Problem Description

Ignatius is building an Online Judge, now he has worked out all the problems except the Judge System. The system has to read data from correct output file and user's result file, then the system compare the two files. If the two files are absolutly same, then the Judge System return "Accepted", else if the only differences between the two files are spaces(' '), tabs('\t'), or enters('\n'), the Judge System should return "Presentation Error", else the system will return "Wrong Answer".

Given the data of correct output file and the data of user's result file, your task is to determine which result the Judge System will return.

 

Input

The input contains several test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow.
Each test case has two parts, the data of correct output file and the data of the user's result file. Both of them are starts with a single line contains a string "START" and end with a single line contains a string "END", these two strings are not the data. In other words, the data is between the two strings. The data will at most 5000 characters.

 

Output

For each test cases, you should output the the result Judge System should return.

 

Sample Input

4START1 + 2 = 3ENDSTART1+2=3ENDSTART1 + 2 = 3ENDSTART1 + 2 = 3ENDSTART1 + 2 = 3ENDSTART1 + 2 = 4ENDSTART1 + 2 = 3ENDSTART1+2=3END

 

Sample Output

Presentation ErrorPresentation ErrorWrong AnswerPresentation Error

题解：此题我当时对结尾标志想了一会，第一反应用kmp 后来想想太麻烦，参考大神代码后，直接简单查询就可以，有的时候就是不用想太多。

代码如下：

#include<iostream>using namespace std;const int maxn = 5000;char inputOrigal[maxn + 5];  //源文件char inputNew[maxn + 5];     //用户文件int lenOri = 0;//  源文件长度int lenNew = 0;  //用户文件长度bool judge(char str[],int n){       /*判断结尾标志  此处很巧妙   因为开头好处理，但是结尾不知道在哪*/if (str[n] == '\n'&&str[n - 1] == 'D'&&str[n - 2] == 'N'&&str[n - 3] == 'E'&&str[n - 4] == '\n') {return true;}return false;}bool judgeChar(char ch) {          /*判断空格 跳格 回车*/if (ch == ' ' || ch == '\t' || ch == '\n')return true;return false;}int main() {int numTest;cin >> numTest;while (numTest--) {char startTag[6];cin >> startTag;if (strcmp(startTag, "START") == 0) {   /*判断开头*/int indexOrigal = 0;getchar();while (1) {      /*存文件*/inputOrigal[indexOrigal] = getchar();if (judge(inputOrigal,indexOrigal)) {break;}indexOrigal++;}lenOri = indexOrigal - 4;/*记录文件长度 此处减去结尾标志*/}cin >> startTag;if (strcmp(startTag, "START") == 0) {int indexOrigal = 0;getchar();while (1) {inputNew[indexOrigal] = getchar();if (judge(inputNew,indexOrigal)) {break;}indexOrigal++;}lenNew = indexOrigal - 4;}bool accepet = true;    bool repretation = true;bool wrong = true;int oriFlag = 0, newFlag = 0;if (lenOri != lenNew)accepet = false;else {int i = 0;while (i < lenOri) {if (inputOrigal[i] != inputNew[i]) {accepet = false;break;}i++;}}while (1) {while (oriFlag < lenOri&&judgeChar(inputOrigal[oriFlag]))oriFlag++;while (newFlag < lenNew&&judgeChar(inputNew[newFlag]))newFlag++;if (oriFlag >= lenOri&&newFlag>=lenNew)break;else if (oriFlag >= lenOri || newFlag>=lenNew) {repretation = false;break;}else if (inputOrigal[oriFlag] != inputNew[newFlag]) {repretation = false;break;}else {oriFlag++;newFlag++;}}if (accepet)printf("Accepted\n");else if(repretation)printf("Presentation Error\n");elseprintf("Wrong Answer\n");}}
