leetcode提交错误

一个是520.Detect Capital
Given a word, you need to judge whether the usage of capitals in it is right or not.

We define the usage of capitals in a word to be right when one of the following cases holds:

All letters in this word are capitals, like "USA".
All letters in this word are not capitals, like "leetcode".
Only the first letter in this word is capital if it has more than one letter, like "Google".
Otherwise, we define that this word doesn't use capitals in a right way.

这是我提交的函数：（有六个样例不能通过，我觉得貌似没有错误）
bool detectCapitalUse(char* word) {
bool j;
int tag=0,i;
int count;
count=strlen(word);
if((word[1]>='A')&&(word[1]<='Z'))
{
for(i=2;i<count-1;i++)
{
if(('A'<=word[i])&&(word[i]<='Z'))
{
tag=tag+1;
}
}
if((tag!=0)&&(tag!=count-3)) j=false;
else j=true;
}
else
{
for(i=1;i<count-1;i++)
{
if(word[i]<='Z') {j=false;return j;}
}
j=true;
}
return j;


}

还有一个557. Reverse Words in a String III（也是自己觉得找不到错误..不能通过） 题目：Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order. Example 1: Input: "Let's take LeetCode contest" Output: "s'teL ekat edoCteeL tsetnoc" 我提交的函数： char* reverseWords(char* s) { int i,k=0,t,j; char c; int a=strlen(s); for(i=1;i<a;i++) { k++; if(s[i]==' '|s[i]=='\"') { if(k%2==0) t=k/2; else t=(k-1)/2+1; for(j=1;j<t;j++) { c=s[i-k+j]; s[i-k+j]=s[i-j]; s[i-j]=c; } if(s[i]=='\"') break; k=0; } } return s; }

能麻烦各位大神看下我的代码，到底哪里出错了吗？

原来真的是输入格式问题，天……
