For each of the Speedrun questions, you will be given a binary-search related problem and a corresponding multiple choice question. The multiple choice questions are related to the techniques and template(s) introduced in the binary search section.
It's recommended that you have gone through at least Find the First True in a Sorted Boolean Array, Monotonic Function and Binary Search Template and a number of example problems in the binary search section.
