What Is Beats in LeetCode?
LeetCode is a popular coding platform used by developers to practice and improve their programming skills. In LeetCode, a concept called “Beats” is introduced that helps measure the efficiency of a solution to a coding problem. But what exactly is “Beats” in LeetCode?
Key Takeaways
- Beats is a metric in LeetCode that measures the efficiency of a solution to a coding problem.
- It compares a solution’s runtime and memory usage against other submissions for the same problem.
- Solutions with lower runtime and memory usage are considered more efficient and receive higher Beats.
Understanding Beats in LeetCode
When you submit a solution to a coding problem on LeetCode, it gets evaluated based on its runtime and memory usage. The platform then compares your solution’s performance against other submissions for the same problem and assigns it a Beats value. This value indicates how efficient your solution is compared to others.
Beats provides a standardized way to compare different solutions and encourages developers to optimize their code.
How Is Beats Calculated?
Beats is calculated by comparing the runtime and memory usage of your solution with the best submissions for the problem. LeetCode uses a reference solution as the baseline for calculating Beats.
The reference solution sets the efficiency benchmark that your solution is measured against.
Beats are assigned based on the inequality criteria below:
- If runtime and memory usage both beat the reference solution, you receive 2 Beats.
- If only runtime or memory usage beats the reference solution, you receive 1 Beat.
- If neither runtime nor memory usage beats the reference solution, you receive 0 Beats.
Why Are Beats Important?
Beats provide developers with a quantitative measure of their code’s performance. By aiming for higher Beats, you strive to optimize your code, making it more efficient in terms of runtime and memory usage.
Improving your Beats not only demonstrates your proficiency in problem-solving but also enhances your ability to write efficient algorithms.
Comparing Solutions with Beats
In LeetCode, you can compare different solutions for the same problem based on their Beats values. This allows you to analyze the efficiency of various approaches and understand the trade-offs between them.
| Solution | Beats | Runtime | Memory Usage |
|---|---|---|---|
| Solution 1 | 2 Beats | 100 ms | 10 MB |
| Solution 2 | 1 Beat | 120 ms | 8 MB |
| Solution 3 | 0 Beats | 150 ms | 12 MB |
Comparing solutions with Beats helps you understand the performance implications of different coding choices.
Summary
Beats in LeetCode is a metric that measures the efficiency of a solution by comparing its runtime and memory usage against other submissions for the same coding problem. Aim for higher Beats to showcase your optimization skills and improve your ability to write efficient algorithms.

Common Misconceptions
Misconception 1: Beats in LeetCode are a measure of performance
One common misconception people have is that the word “beats” in LeetCode refers to the performance of a solution. However, in reality, “beats” indicates how a particular solution compares to the performance of other solutions submitted by LeetCode users. It is not a measure of the solution’s efficiency or speed.
- Beats does not necessarily mean a solution is more efficient.
- Beats is a relative measure, comparing against other solutions.
- Solutions that beat a large number of submissions may still be suboptimal.
Misconception 2: Beats are only based on the runtime of a solution
Another misconception is that beats are solely based on the runtime of a solution. While runtime is one of the factors considered, LeetCode also takes into account factors like memory usage, code complexity, and algorithmic efficacy. A solution with a faster runtime may not necessarily have the best overall performance.
- Memory usage and code complexity also influence beats.
- Algorithmic efficacy can play a significant role in the beats metric.
- The beats metric considers various aspects of a solution’s performance.
Misconception 3: Beats determine the correctness of a solution
Some mistakenly believe that the beats metric determines the correctness of a solution. However, beats only measure how well a solution performs relative to others and do not reflect its validity. A solution that beats many others may still be incorrect or produce incorrect outputs.
- Beats metric does not guarantee the solution is correct.
- Correctness should be validated separately from the beats metric.
- A solution with lower beats may still be correct.
Misconception 4: Beats are equal for all LeetCode problems
One common fallacy is that the beats metric is uniform across all LeetCode problems. In reality, the beats metric varies depending on the problem difficulty, problem constraints, and the quality and quantity of submitted solutions. It is important to consider the specific context of a problem while interpreting the beats metric.
- Beats metric is not constant for different LeetCode problems.
- Beats metric depends on problem difficulty and constraints.
- Quality and quantity of submissions affect the beats metric.
Misconception 5: Beats are the sole measure of solution quality
Solutions that achieve a high beats score are often considered superior. However, it is important to note that beats do not capture all aspects of solution quality. Other factors like code readability, maintainability, and extensibility are equally important but not reflected in the beats metric.
- Beats do not encompass all aspects of solution quality.
- Code readability and maintainability are important but not reflected in beats.
- Extensibility and flexibility are also crucial beyond the beats metric.
