NPRG062 (Introduction to algorithms) [tutorial] - went over homework and then did some things regarding binary heaps and linked lists, i've come to the conclusion that i like heaps, what a silly data structure

NPRG030 (Programming 1) [tutorial] - linked lists, specifically working towards the homework we have where we are given a series of natural numbers and we have to, using a linked list, sort it in a way that first are the sorted evens then sorted odds

NJAZ070 (English for Upper-Intermediate Students I) - i did pretty well on the test! 26/30 with the best score in the class being 27/30, after going over the test answers and the homework we were told about how to structure the essay we're writing in 3 weeks.. i'm a little afraid of it, as i always am with essays, for what if none of the subjects speak to me.. it's going to be an argumentative essay, with the little time left we also did some thing from the book..

no adventure this week because i was feeling really week and also i couldn't find a place i wanted to adventure in..

NMSA230 (Introduction to R programming) - data frames! good way to structure data and work with it it seems, how to merge multiple data frames together, how to make subsets, how to analyse them and the library stargazer, which creates a TeX table from a data frame, around the end we also found out how to extract data from a csv/excel

NPRG062 (Introduction to algorithms) [tutorial] - more big O notation stuff, proofs of various statements like if f(x) has O(g(x)) does g(x) have O(f(x)) and what not, which this specifically i disproved in front of the class, that was rather spiral eyes emoji..

NPRG030 (Programming 1) [tutorial] - two people showed their solution of the homework, the teacher then showed us how to program a select sort and how to use the debugger in vscode, i use vim though.. there was something else but i can't recall what

NJAZ070 (English for Upper-Intermediate Students I) - went over homework and had a listening exercise, there must have been more.. possibly speaking of some form.. idk

this was where it ended last week, but every other week i have one class more, which i will talk about in a bit, but that class starts three and a half hours after english ends.. so to pass the time i went to the airport, which i think was a nice experience

NMSA230 (Introduction to R programming) - the teacher got that aoko aozaki fit, went over some structures like: list, logical, for, character, factor, date and posix time.. some things i thought were curios are you can compare a vector to a value and it compares it component by component and the result is a vector of booleans, you can use apply as a shorthand for a for cycle, factors, in general seem cool, they are for categorical values and working with time is silly
