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
