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:
Question connection: codeforces 455b a lot of games
