1.please write your code in c

2. your code will be judged by loader code

3. make sure to pass the test case

Please write a gettoken function which can isolate sequential tokens in a null-terminated string. The first argument str is a pointer to char which will point to the string that we want to get tokens from. The second argument sep is a string of separator. The first time that gettoken is called, str should be specified; subsequent calls, wishing to obtain further tokens from the same string, should pass a NULL pointer instead.

strtok, strtok_r, strsep is banned in this problem

Input

The first line contains an integer N that indicates the number of lines, followed by N lines of text, each line will be less than 4000 character

Output

Multiple tokens, each separated by a newline

Loader Code

Your code will be judge using this program:

#include

#include

char *strtok(char *s, const char *sep) {

printf("strtok banned ");

exit(1);

}

char *strtok_r(char *str, const char *sep, char **lasts) {

printf("strtok_r banned ");

exit(1);

}

char *strsep(char **stringp, const char *delim) {

printf("strsep banned ");

exit(1);

}

char *gettoken(char *str, const char *sep);

int main() {

char buffer[4096];

char *sep = " \t ;,.?!";

char *word;

int N;

scanf("%d ", &N);

for (int i = 0; i < N; i++) {

fgets(buffer, 4095, stdin);

for (word = gettoken(buffer, sep); word != NULL;

word = gettoken(NULL, sep)) {

printf("%s ", word);

}

}

}
