Grokking the Coding Interview Patterns in C#

Fraction to Recurring Decimal

Explore how to implement a function that converts a fraction given by numerator and denominator into a string, enclosing repeating decimal parts in parentheses. Learn to use hash maps effectively to identify recurring sequences, improve problem understanding, and apply this pattern in coding challenges.

We'll cover the following...

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
