print('\n >>> 65. Valid Number') print(''' A valid number can be split up into these components (in order):

A decimal number or an integer. (Optional) An 'e' or 'E', followed by an integer.

A decimal number can be split up into these components (in order):

(Optional) A sign character (either '+' or '-'). One of the following formats: One or more digits, followed by a dot '.'. One or more digits, followed by a dot '.', followed by one or more digits. A dot '.', followed by one or more digits. An integer can be split up into these components (in order):

(Optional) A sign character (either '+' or '-'). One or more digits. For example, all the following are valid numbers: ["2", "0089", "-0.1", "+3.14", "4.", "-.9", "2e10", "-90E3", "3e+7", "+6e-1", "53.5e93", "-123.456e789"], while the following are not valid numbers: ["abc", "1a", "1e", "e3", "99e2.5", "--6", "-+3", "95a54e53"].

Given a string s, return true if s is a valid number.

Example 1:

Input: s = "0" Output: true Example 2:

Input: s = "e" Output: false Example 3:

Input: s = "." Output: false ''')
