This problem helps you practice core Computer Mathematics fundamentals in a practical way. It builds intuition around compare, fraction, two. Let’s break it down step by step so you can implement it confidently.
Problem Statement
Compare two fractions without floating point. Print , or =.
Input Format
Four integers a b c d.
Output Format
One char: < or > or =.
Constraints
b,d != 0, values fit in 64-bit
Code Solution
This explanation is written for learning purposes and to help beginners understand the concept clearly.
Compare a*d and c*b using integer multiplication. If a*d < c*b print < etc.
Common Mistakes
- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
