Added problem description for future reference
2020-03-28 03:30:25 +01:00

Finished problem 2: sum of even fibonacci numbers
2020-03-28 03:30:48 +01:00
3
Technically was a bug in 3
2020-03-29 04:02:44 +02:00
4
Finished 4, palindrome was 906609

9
Finished 9, easy brute force solution
2020-03-31 00:46:27 +02:00
10
Finished 10, finally learned to write a proper friggin sieve
2020-03-31 00:49:32 +02:00
11
Finished 11, always remember there are 2 diagonals
2020-03-31 15:33:02 +02:00
12
Work in progress, 15 doesn't work like intended
2020-04-07 11:41:01 +02:00
13
This was probably the easiest problem so far, Python is just cheating
2020-04-05 14:48:53 +02:00
14
Found the longest Collatz chain: 837799
2020-04-05 15:36:53 +02:00
15
Finally finished, learned how not init nested array
2020-04-09 02:14:55 +02:00
16
Forgot to add problem description
2020-04-09 02:39:45 +02:00
17
I learned that 18 is spelled as eighteen
2020-04-09 03:02:24 +02:00
18
Finished with a divide and conquer approach, max sum is 1074
2020-04-11 22:38:23 +02:00
19
Was lazy, used datetime library for this
2020-04-11 22:56:17 +02:00
20
Forgot problem description
2020-04-11 23:08:54 +02:00
21
Python is frustratingly weird with equality checks
2020-04-12 01:09:31 +02:00
22
Finished 23, pretty darn slow and ugly solution
2020-04-14 00:37:45 +02:00
23
Finished 23, pretty darn slow and ugly solution
2020-04-14 00:37:45 +02:00
24
Really fast solution, not bruteforce
2020-04-14 18:36:37 +02:00
25
First 25 done. I still feel dirty for using Python
2020-04-14 21:14:18 +02:00
26
Finally finished 26, think I did it good enough
2020-11-08 01:57:52 +01:00
27
Ok so this solution is supersuperslow but it worked
2020-11-08 22:09:34 +01:00
28
That one was easy
2020-11-08 22:45:13 +01:00
29
Very easy to do in Python
2020-11-08 22:54:08 +01:00
30
Easy bruteforce solution
2020-11-08 23:28:22 +01:00
31
Standard coin change algorithm
2020-11-09 00:35:30 +01:00
32
Solved the pandigits, tried to do it way more complicated than necessary at first
2021-02-13 20:14:10 +01:00
33
Manually edit end result to simplified fraction
2021-02-22 20:51:32 +01:00
34
34 done, that was way too easy haha
2021-02-22 21:04:13 +01:00
35
35 done, slow but it works
2021-02-22 21:35:25 +01:00
36
Finished 36, was really easy
2021-02-23 16:33:00 +01:00
37
Dumb solution is quick enough so me do dumb solution
2021-02-25 23:37:52 +01:00
38
Found highest pandigital concat product
2021-02-26 00:22:50 +01:00
39
Finished the pythagorean triangle circumferences
2021-02-26 00:52:25 +01:00
40
Basically just indexing, god python is easy
2021-02-26 01:02:00 +01:00
41
Oof I feel ashamed by having written this code, 41
2021-02-26 01:43:39 +01:00
42
42 was too easy, can't be the answer to everything
2021-02-27 22:46:09 +01:00
43
43 done, not too bad
2021-02-27 23:34:17 +01:00
44
Not even that slow of a solution for 44
2021-03-01 23:45:01 +01:00
45
45 really easy once you can quickly verify pentagonal numbers
2021-03-02 00:03:01 +01:00
46
Finished 46 with quite a quick algorithm
2021-03-06 00:57:36 +01:00
47
Quite a slow solution for 47, but it works
2021-03-06 01:32:47 +01:00
48
Remember that 0^0 is not 0, or at least not implemented as such (what it truly is is a mystery)
2021-03-06 17:51:52 +01:00
49
Tricky one, but quick code
2021-03-06 18:43:50 +01:00
50
Misinterpreted that questin multiple times, finally just did an exhaustive search
2021-03-12 01:11:59 +01:00
51
Strictly speaking this algorithm has an O(n^2) part in it, but it runs under a second so...
2021-04-06 01:16:05 +02:00
52
52 was so easy that at first I thought my code was bugged
2021-04-06 01:56:27 +02:00
53
Gotta love these easy ones
2021-04-06 10:19:08 +02:00
54
I wouldn't call it hard, it was just a metric shitton of work to get all cases handled correctly
2021-04-08 16:09:20 +02:00
55
Not that hard, just a loopty loop and keep track of which ones you did already
2021-04-08 18:11:54 +02:00
56
Brute forcing all day
2021-04-09 16:16:42 +02:00
57
Had it run 10 times too many integers woops, but still easy to solve
2021-04-10 00:48:31 +02:00
58
For some reason the execution time is very variable, also I learned that sympy isprime exists
2021-04-11 02:14:57 +02:00
59
From now on programming in C++, no Python cheats anymore
