Given two strings s and t, each of which represents a non-negative rational number, return true if and only if they represent the same number. The strings may use parentheses to denote the repeating part of the rational number.

\n\n

A rational number can be represented using up to three parts: <IntegerPart>, <NonRepeatingPart>, and a <RepeatingPart>. The number will be represented in one of the following three ways:

\n\n\n\n

The repeating portion of a decimal expansion is conventionally denoted within a pair of round brackets. For example:

\n\n\n\n

 

\n

Example 1:

\n\n
\nInput: s = "0.(52)", t = "0.5(25)"\nOutput: true\nExplanation: Because "0.(52)" represents 0.52525252..., and "0.5(25)" represents 0.52525252525..... , the strings represent the same number.\n
\n\n

Example 2:

\n\n
\nInput: s = "0.1666(6)", t = "0.166(66)"\nOutput: true\n
\n\n

Example 3:

\n\n
\nInput: s = "0.9(9)", t = "1."\nOutput: true\nExplanation: "0.9(9)" represents 0.999999999... repeated forever, which equals 1.  [See this link for an explanation.]\n"1." represents the number 1, which is formed correctly: (IntegerPart) = "1" and (NonRepeatingPart) = "".\n
