Given two sparse matrices A and B, return the result of AB. You may assume that A's column number is equal to B's row number. Example: A = [ [ 1, 0, 0], [-1, 0, 3] ] B = [ [ 7, 0, 0 ], [ 0, 0, 0 ], [ 0, 0, 1 ] ] | 1 0 0 | | 7 0 0 | | 7 0 0 | AB = | -…

题目大意: 给出a, b两个用字符串表示的虚数,求a*b 题目思路: 偷了个懒,Python3的正则表达式匹配了一下,当然acm里肯定是不行的 class Solution: def complexNumberMultiply(self, a, b): """ :type a: str :type b: str :rtype: str """ match = re.search(r'([+-]*\d+)[+-]([+-]*\d+)i$', a)…
