Just write two integers, for the numerator and denominator. That’s great! But alas, they are no good at all for irrational numbers like pi, or the square root of 2. I could, of course, write a fraction that’s close to the irrational number, such as 22/7 as an approximation of pi. But th...

Performance comparison: counting words in Python, Go, C++, C, AWK, Forth, and Rust March 2021 Summary: I describe a simple interview problem (counting frequencies of unique words), solve it in various languages, and compare performance across them. For each language, I’ve included a simple, idiomatic solution as well as a more optimized approach via profiling. I’ve conducted many coding interviews over the past few years, and one of the questions I like to ask is this: Write a program to count the frequencies of unique words from standard input, then print them out with their frequencies,...
