1.2.题目内容
2.解题分析
题目输入输出格式描述不清晰。
2.1.分析(1)
所有数据都完成输入,然后再输出(解法1,内存可能不够(AC通过))
2.2.分析(2)
待测数据输完一行立马输出一行结果(解法2,内存够(没通过))
2.3.总结
两种写法都写了,最后以第一种输入输出格式通过,后台没有内存超出的数据
3.解题代码
3.1.解法1(AC)
//解法1,内存可能不够,对题意通用性高(AC通过)
#include<iostream>
#include<map>
#include<cstdio>
using namespace std;
int main() {
string s[3005], s0, s1 = "", s2 = "";
map<string, string> f;
f["czy"] = "cml";
cin >> s1;
while(s2 != "BEGIN") {
cin >> s1 >> s2;
f[s2] = s1;
}
int n = 0;
char ch[3005];
do {
cin >> s[++n];
ch[n] = getchar();
}while(s[n] != "END");
for(int i = 1; i < n; i++) {
s0 = "";
for(int j = 0; j < s[i].size(); j++) {
if(s[i][j] >= 'a' && s[i][j] <= 'z') {
s0 += s[i][j];
} else {
if(f[s0] != "") cout << f[s0];
else cout << s0;
cout << s[i][j];
s0 = "";
}
}
if(f[s0] != "") cout << f[s0];
else cout << s0;
if(ch[i] == '\n') cout << "\n";
else cout << " ";
}
}
3.2.解法2(WA)
//解法2,内存能够,因为题意有歧义可能不能这样解(没通过)
#include<iostream>
#include<map>
#include<cstdio>
#include<cstring>
using namespace std;
int main() {
string s0, s1 = "", s2 = "";
map<string, string> f;
f["czy"] = "cml";
cin >> s1;
while(1) {
cin >> s1 >> s2;
if(s2 == "BEGIN") break;
f[s2] = s1;
}
char s[3005];
getchar();
while(1) {
gets(s);
if(s[0] == 'E' && s[1] == 'N' && s[2] == 'D') break;
s0 = "";
for(int i = 0; i < strlen(s); i++) {
if(s[i] >= 'a' && s[i] <= 'z') {
s0 += s[i];
} else {
if(f[s0] != "") cout << f[s0];
else cout << s0;
cout << s[i];
s0 = "";
}
}
cout << endl;
}
}
