根据廖雪峰老师的评论区摘录. 1: def triangles(): L = [1] while True: yield L L1 = [0] + L[:] L = [L[i]+L1[i] for i in range(len(L))] + [1] 2: def triangles(): L = [1] while True: yield L L.append(0); L = [L[i-1] + L[i] for i in range(len(L))] 输出结果: # 期待输出: # [1] #…
Given a non-negative integer numRows, generate the first numRows of Pascal's triangle. In Pascal's triangle, each number is the sum of the two numbers directly above it. Example: Input: 5 Output: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 给定一个非负…
Pascal's triangle (1过) Given numRows, generate the first numRows of Pascal's triangle. For example, given numRows = 5, Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 给定一个非负整数 numRows,生成杨辉三角的前 numRows 行. 在杨辉三角中,每个数是它左上方和右上方的数的和. 示例: 输入: 5 输出:…
