而前面的点因为距离限制 ,有可能只能跳到index = 1,而不可以跳到index = 2, 3.所以 将倒数第二步设置在index = 1可以得到最多的解。 View Code SOLUTION 2:(2015.1.13 redo) Leetcode增强test case之后,前面的算法不能通过,感谢http://fisherlei.blogspot.com/2012/12/leetcode-jump-ii.html的灵感: [...
于是有了下面的代码,小数据集直接就AC了,大数据集却卡住了,极端情况下这个算法的复杂度是O(N2),但是侥幸心理让我还是写了这个解法,但是还是没过,悲催,先记录一下吧。 classSolution { public: intjump(intA[],intn) { // Start typing your C/C++ solution below // DO NOT write int main() function ...

数组中的每个元素代表你在该位置可以跳跃的最大长度。 判断你是否能够到达最后一个下标,如果可以,返回 true ;否则,返回 false。 示例1: 输入:nums = [2,3,1,1,4] 输出:true 解释:可以先跳 1 步,从下标 0 到达下标 1, 然后再从下标 1 跳 3 步到达最后一个下标。 示例2: 输入:nums = [3,2,1...
