A list of positive integers has a unique mode, which occurs exactly times. What is the least number of distinct values that can occur in the list?
Solution
To minimize the number of values, we want to maximize the number of times they appear. So, we could have 223 numbers appear 9 times, 1 number appear once, and the mode appear 10 times, giving us a total of 223 + 1 + 1 =
