run-length Interview Questions

This Google interview question challenges candidates to filter a vocabulary list by matching words against a sequence produced by a faulty keyboard where keys stick and repeat characters. The task evaluates your ability to handle custom sequence comparisons, grouping adjacent identical elements, and validating length constraints between candidate strings and corrupted inputs. You will need to design an efficient routine that checks whether each dictionary term can successfully map to the jammed output.

Featured in recent Goldman Sachs technical assessments, this problem challenges you to scan an integer array and count every contiguous subsegment of a specific size that maintains a strictly ascending order. It serves as a fantastic test of sliding window techniques, sequence tracking, and efficient array iteration. Mastering this pattern helps build confidence for similar subsegment query tasks.
