Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.
Please note that the string does not contain any non-printable characters.
Example:
Input: "Hello, my name is John"
Output: 5 找出连续字符串个数(注意示例中Hello,后面有空格)
解题思路:
设立标志位,遍历字符串,当标志位从0变为1时,count++
int countSegments(char* s) {
int flag=;
int i=;
int count=;
while(s[i])
{
if(!flag&&!(s[i]==' '||s[i]=='\t'))
{
flag=;
count++;
}
else
if(flag&&(s[i]==' '||s[i]=='\t'))
flag=;
i++;
}
return count;
}
