‘遍历’ (biàn lì) is a verb meaning 'to traverse' or 'to iterate'—especially in computing contexts. It combines 遍 (biàn), meaning 'all over', 'throughout', or 'every instance', and 历 (lì), meaning 'to experience', 'to go through', or 'to pass through'. Together, they convey the idea of systematically visiting or processing each element in a data structure—such as an array, list, tree, or graph—once and in a defined order.

This term is highly technical and rarely used outside programming, algorithms, or computer science education. It’s common in discussions about search algorithms (e.g., depth-first or breadth-first traversal), loop structures, and data processing logic. Unlike everyday verbs like ‘查看’ (to view) or ‘读取’ (to read), ‘遍历’ emphasizes completeness and systematic coverage—not just looking at something, but methodically accessing every part. Learners should note it's almost never used for physical movement or casual inspection.
