<p>Given two strings <code>s</code> and <code>t</code>, each of which represents a non-negative rational number, return <code>true</code> if and only if they represent the same number. The strings may use parentheses to denote the repeating part of the rational number.</p> <p>A <strong>rational number</strong> can be represented using up to three parts: <code><IntegerPart></code>, <code><NonRepeatingPart></code>, and a <code><RepeatingPart></code>. The number will be represented in one of the following three ways:</p> <ul> <li><code><IntegerPart></code> <ul> <li>For example, <code>12</code>, <code>0</code>, and <code>123</code>.</li> </ul> </li> <li><code><IntegerPart><strong><.></strong><NonRepeatingPart></code> <ul> <li>For example, <code>0.5</code>, <code>1.</code>, <code>2.12</code>, and <code>123.0001</code>.</li> </ul> </li> <li><code><IntegerPart><strong><.></strong><NonRepeatingPart><strong><(></strong><RepeatingPart><strong><)></strong></code> <ul> <li>For example, <code>0.1(6)</code>, <code>1.(9)</code>, <code>123.00(1212)</code>.</li> </ul> </li> </ul> <p>The repeating portion of a decimal expansion is conventionally denoted within a pair of round brackets. For example:</p> <ul> <li><code>1/6 = 0.16666666... = 0.1(6) = 0.1666(6) = 0.166(66)</code>.</li> </ul> <p> </p> <p><strong>Example 1:</strong></p> <pre> <strong>Input:</strong> s = "0.(52)", t = "0.5(25)" <strong>Output:</strong> true <strong>Explanation:</strong> Because "0.(52)" represents 0.52525252..., and "0.5(25)" represents 0.52525252525..... , the strings represent the same number. </pre> <p><strong>Example 2:</strong></p> <pre> <strong>Input:</strong> s = "0.1666(6)", t = "0.166(66)" <strong>Output:</strong> true </pre> <p><strong>Example 3:</strong></p> <pre> <strong>Input:</strong> s = "0.9(9)", t = "1." <strong>Output:</strong> true <strong>Explanation:</strong> "0.9(9)" represents 0.999999999... repeated forever, which equals 1. [<a href="https://en.wikipedia.org/wiki/0.999..." target="_blank">See this link for an explanation.</a>] "1." represents the number 1, which is formed correctly: (IntegerPart) = "1" and (NonRepeatingPart) = "". </pre> <p> </p> <p><strong>Constraints:</strong></p> <ul> <li>Each part consists only of digits.</li> <li>The <code><IntegerPart></code> does not have leading zeros (except for the zero itself).</li> <li><code>1 <= <IntegerPart>.length <= 4</code></li> <li><code>0 <= <NonRepeatingPart>.length <= 4</code></li> <li><code>1 <= <RepeatingPart>.length <= 4</code></li> </ul>
