Global Structuring Analyst Interview Questions and Answers

Minimize tries to guess a number between 1 and 64 using a binary search strategy.

• Use binary search: Guess the middle number (32) first.

• If the guess is too high, focus on the lower half (1-31).

• If the guess is too low, focus on the upper half (33-64).

• Repeat the process, halving the range each time.

• In the worst case, it takes 6 tries (2^6 = 64).
