// 自写逻辑，遍历所有匹配的子字符串坐标
private static void forMatchIdx(String str1, String str2)
char[] arr1 = str1.toCharArray();
char[] arr2 = str2.toCharArray();
f1: for (int i = 0; i < arr1.length; i++)
for (int j = 0; j < arr2.length; j++)
if (arr1[i + j] != arr2[j])
continue f1;


System.out.println("idx:" + i);
