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.
A rational number can be represented using up to three parts: , , and a . The number will be represented in one of the following three ways:
The repeating portion of a decimal expansion is conventionally denoted within a pair of round brackets. For example:
Examples
Example 1
Input: s = "0.(52)", t = "0.5(25)"
Output: true
Explanation: Because "0.(52)" represents 0.52525252..., and "0.5(25)" represents 0.52525252525..... , the strings represent the same number.
Example 2
Input: s = "0.1666(6)", t = "0.166(66)"
Output: true
Example 3
Input: s = "0.9(9)", t = "1."
Output: true
Explanation: "0.9(9)" represents 0.999999999... repeated forever, which equals 1. [See this link for an explanation.]
"1." represents the number 1, which is formed correctly: (IntegerPart) = "1" and (NonRepeatingPart) = "".
Constraints
Each part consists only of digits.
The <IntegerPart> does not have leading zeros (except for the zero itself).
1 <= <IntegerPart>.length <= 4
0 <= <NonRepeatingPart>.length <= 4
1 <= <RepeatingPart>.length <= 4
