Questions reported for Yandex¶
Practical coding¶
- Find a pair of numbers in an array with a given sum; clarify the conditions, test the code and discuss complexity and edge cases.
- Coding · Asked at: Yandex ✅
- Tests: Whether basic data-structure fluency, testing and edge-case discipline hold up in live coding.
- A strong answer covers:
- Clarify sortedness, duplicates, negatives, reuse of one element, and whether to return values, indices or all pairs.
- Use a hash set in O(n) time, or two pointers on sorted input with O(1) extra space.
- Test empty and single-element arrays, no valid pair, a target equal to twice one value, and overflow.
