[理工] 想要詢問一題鴿籠
A wheel of fortune has the integer from 1 to 25 placed on it in a random manne
r. Show that regardless of how the numbers are positioned on the wheel, there
are three adjacent numbers whose sum is at least 39.
這一題我先把1~25的數字分成1~12和13~25兩堆,然後當成1~25任挑三
個數字相加去作,但是接下來找worst case不會找,跪求好心的大大解答。
