UVaOJ 272 - TEX Quotes

问题描述

解法一：模拟

模拟读入，可一边读一边处理（逐字符或逐行地），关键是设置一个标志变量（此处为 start ）判断引号类型。

#include <bits/stdc++.h>

using namespace std;

int main() {
  char ch;
  bool start = true;
  while ((ch = getchar()) != EOF) {
    if (ch == '"') {
      cout << (start ? "``" : "''");
      start = !start;
    } else {
      cout << ch;
    }
  }
  return 0;
}

#include <bits/stdc++.h>

using namespace std;

int main() {

char ch;

bool start = true;

while ((ch = getchar()) != EOF) {

if (ch == '"') {

cout << (start ? "``" : "''");

start = !start;

} else {

cout << ch;

}

return 0;

}

import sys

start = True

for line in sys.stdin:
    for ch in line:
        if ch == "\"":
            print("``" if start else "''", end='')
            start = not start
        else:
            print(ch, end="")

import sys

start = True

for line in sys.stdin:

for ch in line:

if ch == "\"":

print("``" if start else "''", end='')

start = not start

else:

print(ch, end="")
