代码：字符串中连续与重复字符判断

字符串操作：

int consecutiveCharMaxCount( char *str)

{

char *pstr = NULL;

char *p = NULL;

int value = 0;

int incN = 1;

int decN = 1;

int maxCount = 0;

char chrp = 0;

char chrn = 0;

if(str == NULL)

return ERROR;

p = str;

while(*p != ‘\0‘)

{

pstr = p;

incN = 1;

decN =1;

value = 0;

while(*pstr != ‘\0‘)

{

chrp = *pstr;

chrn = *(++pstr);

value = chrp - chrn;

if(value == 1)

incN++;

else

{

maxCount = (maxCount>=incN)?maxCount:incN;

incN = 1;

}

if(value == -1)

decN++;

else

{

maxCount = (maxCount>=decN)?maxCount:decN;

decN = 1;

}

}

p++;

}

return maxCount;

}

int repeatedCharMaxCount( char *str)

{

char pchar[2] = {0};

char *pindex = NULL;

char *pstr = NULL;

int n = 0;

int maxCount = 0;

if(str == NULL)

return ERROR;

pstr = str;

while(*pstr != ‘\0‘)

{

memset(pchar,0,2);

pchar[0] = *pstr;

pindex = index(pstr,pchar[0]);

n = strspn(pindex,pchar);

maxCount = (maxCount>=n)?maxCount:n;

pstr++;

}

return maxCount;

}
