| Feb 7 | The review material of test 1 and its solution is posted. |
| Feb 6 | For part 1, homework 3, it is fine to output all results, including min, max, median and modes, on one line. |
| Feb 6 | The submission for part of homework 3 is reopened. When submitting part 2 of the homework, please include only Sudoku.h,Sudoku.cpp and an optional readme.txt file (if there is anything you would like to explain about your solution) in your zip file. We will use our own version of hw3_part2.cpp to compile and run your program. |
| Feb 5 | The submission for part 2 of homework 3 is temporarily closed. It might be opened tonight or tomorrow. |
| Feb 4 | Two clarifications for HW 3, part 1: 1. You may use an integer to count the values before allocating an array. 2. If ptr points to the start of an array of n integers, then std::sort( ptr, ptr+n ) sorts the integers. |
| Feb 4 | For part 2 of homeowork 3 (the Sudoku problem), you may assume that N is at least 2 and at most 10. |
| Feb 2 | Many students did poorly on the "O" notation analysis in HW 1. As a result, we have made it extra credit by lowering the score that earns 100% credit to 57.
The hw solution (.cpp file) is now posted. The algorithm sorts the keywords vector only, at a cost of O(M log M). For each of the N search words, an O(log M) binary earch is performed to look for the keyword, giving O(N log M). The final scanning of the keyword vector is linear, i.e. O(M). Combined, the total is O(N log M) because N > M. This is faster than any algorithm that might involve sorting of the search words. |
| Feb 2 | Homeowork 3 is posted. It is due on 11:59:59pm, Feb 8. |
| Feb 2 | Lecture notes 4 is posted. |
| Jan 31 | When submitting your homework, if the result comes out as "Running test#1....OK!" "Congratulations, your submission validated successfully" It means that your output is the same as the expected one. |
| Jan 31 | The readme file of homework 2 is posted. |
| Jan 30 | It seems that many students did not know how to approach the order notation analysis part of the assignment. As a result, we are making it extra credit by lowering the total points for 100% credit to 57. |
| Jan 30 | Note of lecture 3 is posted. |
