Problem: Fraction to Recurring Decimal

Medium
30 min
Explore how to implement a function that converts a fraction to its decimal string representation, correctly identifying and enclosing repeating decimals. Understand the use of hash maps to track remainders and efficiently handle recurring sequences. This lesson helps you build skills to solve related interview problems with clarity and precision.

Statement

Given the two integer values of a fraction, numerator and denominator, implement a function that returns the fraction in string format. If the fractional part repeats, enclose the repeating part in parentheses.

Constraints:

  • denominator !=0!= 0
  • 105-10^{5} \leq numerator, denominator 1051\leq 10^{5} - 1
