Sample Name1Sample Link1AC548632502YesMathSolution in mind is O(n^2): for each pair of points, get the equation of the straight line linking between them, and add 2 to its count. Print the count of the line having the max count. Problem is how to hash a line equation (coefficients are double).

My Performance Notes: This is so bad performance. Needed many submissions per problem. Always submit as if you are in real contest. Submit to AC, not to see if we will pass or not. Target AC from 1st submission. Think more before submission.

Sample Name2Sample Link2AC15103520702NoImplI had to check the editorial

My Performance Notes:
This is so bad performance. He thought for little time and continued thinking while coding. As a result, much debug time too. RULE: Think More, Code Faster
5
Sample Name3Sample Link3AC152041302YesGraphPlease always write and study your timings.

My Performance Notes: This is so good performance. 1st submission. Thinking is the higher. Code/Debug is so low. By time, thinking column will be improved.

For many beginners, the colored problems (such as UVA ones) are hard.
Please do the following:
- Listen to the video 2-3 times. If still don't understand, search for web materials
- Try the problems. If can't, checkout solutions/videos
- If still hard, just skip. Once finished A do the same in B.
- After B, come back to these colored ones and give another trial
- Move to C1, and so on
- Take it easy to learn :)
