isMatch("ab", ".*") ? true
请赐教！ | J****3
发帖数: 427 | 2 It seems that some readers are confused about why the regex pattern ".*"
matches the string "ab". ".*" means repeat the preceding element 0 or more
times. Here, the "preceding" element is the dot character in the pattern,
which can match any characters. Therefore, the regex pattern ".*" allows the
dot to be repeated any number of times, which matches any string (even an
empty string). | s*****p
