RB_CH01_Q016. Competitive number-calling game

difficulty 1500·answer type: strategy·Not solved

Problem

You and I are to play a competitive game. We shall take it in turns to call out integers. The first person to call out '50' wins. The rules are as follows: 1) The player who starts must call out an integer between one and 10, inclusive; 2) A new number called out must exceed the most recent number called by at least one and by no more than 10. For example, if the first player calls out 'nine,' then the range of valid numbers for the opponent is 10 to 19, inclusive. Do you want to go first, and if so, what is your strategy?
