Summary

Practiced one Go algorithm problem in leetcode, starting with a straightforward extra-array implementation and then adding an in-place variant that packs old and new values into each array slot with modulo and division. Total changes: 1 file touched, +58/-0 across 2 commits.

Content Signals

• Medium: In-place array transformations can use modulo/division to temporarily store two values in one integer. Rationale: The second commit adds a concrete O(1)-space follow-up solution for LeetCode 1920, which is a useful small teaching example.

• No strong signal: This was a focused algorithm-practice day rather than a larger product or project arc. Rationale: The work is valuable as a learning note, but the evidence is limited to one problem and one file.

leetcode

Solved LeetCode 1920, "Build Array from Permutation," in Go. The first commit added the direct readable solution with an output array; the second commit added the more memory-conscious approach that encodes both the original and computed values in the input array before unpacking them.
