对两个字符串进行字符匹配
This code checks if a given string (represented by the variable 'a') contains exactly 11 digits. The backslashes before the 'd' indicate that it is a digit character, and the curly braces indicate the exact number of occurrences expected. Therefore, this code will return true if 'a' consists of exactly 11 digits, and false otherwise.
