Question

Predict output when iterating ordered keys

PracHub · Accepted Answer

This question evaluates understanding of ordered maps, iteration semantics, reverse traversal and accumulation of values in code. It is commonly asked in Coding & Algorithms interviews to test the ability to reason about iteration order, sentinel return values and summation behavior, and it examines practical application of data-structure semantics rather than purely abstract theory.
