Space the shelf markers
Before you start this intermediate track
Numeric arrays and functions. Work with ranges, broadcasting, and matrix coordinates.
Guided code reading and debugging. Runnable coding challenges are available in JavaScript, Python, and SQL.
Understand it, then try it.
Julia ranges can describe evenly spaced numbers without writing every value. The three-part form is start:step:stop, so the middle number controls the gap between markers. collect materializes the range as a vector. This lets a workshop generate a repeatable marking pattern from a few clear values.
spacing = 4markers = 3:spacing:15positions = collect(markers)println(join(positions, " / "))Each mission is a standalone Julia 1.x script using Base. Arrays use their standard one-based indices. Run a single snippet with julia; no packages or input files are required.
Track the values line by line. Predict the result before running this example in your own editor.
