Easy! 题目描述: 假设你正在爬楼梯。需要 n 步你才能到达楼顶。 每次你可以爬 1 或 2 个台阶。你有多少种不同的方法可以爬到楼顶呢? 注意:给定 n 是一个正整数。 示例 1: 示例 2: 解题思路: 这道题目实际上跟斐波那契数列非常相似,假设梯子有n层 ...
On a staircase, the i-th step has some non-negative cost cost[i] assigned (0 indexed). Once ...
题目翻译 有一个楼梯,第i阶用cost[i](非负)表示成本。现在你需要支付这些成本,可以一次走两阶也可以走一阶。 问从地面或者第一阶出发,怎么走成本最小。 测试样例 详细分析 现在用step[i]表示走到第i阶的成本,要求step[i],我们只需在"到前一阶的成本+当前阶成本 ...
