Two friends, Elaine and Tom, are playing a guessing game with each other. Elaine thinks of an integer in her mind and Tom needs to guess the number. Tom can ask a question as follows: Is your number greater than or equal to 5 (or any other specified integer)? Then Elaine has to reply yes or no based on the comparison results of the two numbers.

Design an algorithm, in pseudo-code to help Tom find that number quickly.
