Given an array of non-negative integers, you is initially positioned at the first index of the array.Each element of the array represents your maximum jump length is at that position.Determine if you is able to reach the last index.For example:A = [2,3,1,1,4] , return true .A = [3,2,1,0,4] , return false .Note that the number on each bit here is the maximum length that can be jumped, should use greedy strategy, see other people's implementation, code as follows, think about it later:1 classSolut
There is a list of sorted integers from 1 to N. Starting from left to right, remove the first number and every other number afterward until you reach the end of the list.Repeat the previous step again, but this time from right to left, remove the right most number and every other number from The remaining numbers.We keep repeating the steps again, alternating left-to-right and right-to-left, until a single number remains.Find the last number, the remains starting with a list of length n.Example:

Given n represents a string set. Given K, the game is played K times, followed by N strings. Starting from each board, the string is an empty string, and then the two append characters at the end in turn to ensure that the new string is the prefix of a string in the set and cannot be input by the operator, the new round begins with the previous sentence.

, now give us a heap of stones, ask us whether we can win. Then we analyze from the very beginning, because we first take, then 3 within (including 3) of the stones, we directly win, if a total of 4, then we must lose, because no matter we take a few, the next person can be taken out at once. If a total of 5, we win, because we can take one, and then become 4 to let others take, according to the above analysis we win, so we list 1 to 10 cases are as follows:1 Win2 Win3 Win4 Lost5 Win6 Win7 Win8
