LeetCode 刷题问题描述
解决代码：
public static int numJewelsInStones(String J, String S) {
int K = 0,m = 0;int l=0;int ln = 0;
int num = 0;
int result =0;
int jlenth = J.length();
int slenth = S.length();
while(jlenth>l) {
char c = J.charAt(K);
while(slenth>ln) {
char s = S.charAt(m);
if(c-s==0) {
num++;
result = num;
}
m++;
ln++;
}
K++;
l++;
ln = 0;
m = 0;
}
return result;
}
