jefclaes.be Profile

Title:Jef Claes - On software and life Description:Visualizing some data earlier this week I had to compute the running total of a sequence of numbers. For example, if the input sequence was [ 100; 50; 25 ] the result of the computation would be a new sequence of [ 100; 150; 175 ]. Muscle memory made me take a procedural approach, which works, but made me wonder if I could get away with less lines of code and without mutable state.
