Leetcode—2586.统计范围内的元音字符串数
实现代码
class Solution {
public:
int vowelStrings(vector<string>& words, int left, int right) {
int ans = 0;
for(int i = left; i <= right; i++) {
string s = words[i];
int n = s.size();
char head = s[0];
char rear = s[n - 1];
int flag1 = 0;
int flag2 = 0;
if(head == 'a' || head == 'e' || head == 'i' || head == 'o' || head == 'u') {
flag1 = 1;
}
if(rear == 'a' || rear == 'e' || rear == 'i' || rear == 'o' || rear == 'u') {
flag2 = 1;
}
if(flag1 && flag2) {
ans++;
}
}
return ans;
}
};
运行结果
