When comparing strings, comparisons are typically made following these rules:<\/p>\n

    \n
  1. Firstly, compare the lengths of the strings, where the string with the longer length is greater than the string with the shorter length.<\/li>\n
  2. If the lengths of two strings are equal, then compare the characters at corresponding positions based on their ASCII values.<\/li>\n
  3. Compare characters at the same position in two strings, if the ASCII value of a character in one string is greater than the corresponding character in the other string, then that string is larger.<\/li>\n
  4. If the string contains both letters and numbers, the ASCII value of the letters is greater than the ASCII value of the numbers.<\/li>\n
  5. If one string is a prefix of another string, then the shorter string is less than the longer string.<\/li>\n<\/ol>\n

    By comparing according to the above rules, we can determine the relative size of the two strings.<\/p>\n","protected":false},"excerpt":{"rendered":"
