Solution: Equal Rational Numbers

Explore how to compare two rational numbers given as strings that may include repeating decimal parts. Learn to convert them into fractions and check for equality by reducing fractions to their simplest form. Understand the algebraic approach to handle repeating decimals for accurate comparison.

Statement

Given two strings s and t, each representing 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: <IntegerPart>, <NonRepeatingPart>, and <RepeatingPart>. The number will be expressed in one of the following three formats:

  • <IntegerPart>

    • For example, 1212 ...
