How can we avoid time limit exceeded in HackerEarth?
Why do I get Time Limit Exceeded (TLE)? The second most common cause of TLE is that your method of reading input and writing output is too slow. In Java, do not use a Scanner; use a BufferedReader instead. In C++, do not use cin/cout – use scanf and printf instead.
How do I practice coding?
Here’s my strategy to improve coding skills outside of class and work:
- Practice online.
- Read code written by someone else.
- Try out different ways to do the same thing.
- Put your code through a debugger.
- Take an online course.
- Use open source software.
- Join a team.
How can we reduce time complexity of code?
Reducing Cyclomatic Complexity
- Use small methods. Try reusing code wherever possible and create smaller methods which accomplish specific tasks.
- Reduce if/else statements. Most often, we don’t need an else statement, as we can just use return inside the ‘if’ statement.
How do you handle TLE?
Change methods of Input-Output: You must choose proper input-output functions and data structure that would help you in optimization.
- In C++, do not use cin/cout – use scanf and printf instead.
- In Java, do not use a Scanner – use a BufferedReader instead.
How to optimize your code using appropriate algorithms?
1. Optimize your Code using Appropriate Algorithm For any code you write, you should always take some time to think through and pick the right algorithm to use for your specific scenario. The problem we are going to analyze for this example is to find a maximum value of the function in a two dimensional segment.
How to optimize your code to make it run faster?
There is always more room for improvement to make your code run faster. Sometime we can use certain programming tricks to make a code run faster at the expense of not following best practices such as coding standards, etc. Try to avoid implementing cheap tricks to make your code run faster. 1. Optimize your Code using Appropriate Algorithm
What to do if your algorithm is not working?
Optimize your Algorithm: If nothing works after all this, then you should try changing the algorithm or the approach you are using to solve your problem. Generally, the internal test cases are designed in such a way that you will be able to clear all of them only if you choose the best possible algorithm.
Why does my code take so long to execute?
Server Configuration: The exact time taken by the code depends on the speed of the server, the architecture of the server, OS, and certainly on the complexity of the algorithm. So different servers like practice, CodeChef, SPOJ, etc., may have different execution speeds.
