Ha ha! I worked in one of these matchbox factories as a kid. My dad had dropped me off at my grandpa's for summer vacation in the village. I was not a particularly good kid. So my grandpa took me to the match factory in the morning and

usaco explicitly nudges you towards C++ on the first page itself. problems are graded on running time, even with moderately large datasets, Python simply doesn’t make the cut. So most high schoolers end up using C++ for usaco, and Java for

its been a long time, but when i was taught this material, i was told there are only 3 cases - x+y=1, x+y=2 clearly has no solution since two numbers can’t simultaneously add to both one and two. x+y=1,2x+2y=2 clearly has infinitely many so

Author has computed BBMI (baby baby money index) but mistakenly calls it BMI. If he divides the BBMI by the TFR, one B goes away and you get the true BMI which is a different ranking altogether. For bonus points you can compute which countr

Amazing story. I enjoyed reading this so much. The sad fact that this was written in 1966 - like the gentleman advocated for gutting the public school system 6 decades ago, and only now we are getting around to the business of defunding the

You are deliberately missing the point and confusing X with ‘something that looks like X’. For eg., using QBasic, you can pick some random spot on the monitor and have a white dot show up at that spot. What you end up doing is directly wri
