解题思路:几乎和【leetcode】719. Find K-th Smallest Pair Distance的方法一样。只不过一个是减法一个是乘法,还有一点区别是【leetcode】719. Find K-th Smallest Pair Distance中i-j和j-i只算一个元素,而本题中i*j与j*i算两个元素。 代码如下: classSolution(object):deffindKthNumber(self, m, n, ...
Nearly every one have used theMultiplication Table. But could you find out thek-thsmallest number quickly from the multiplication table? Given the heightmand the lengthnof am * nMultiplication Table, and a positive integerk, you need to return thek-thsmallest number in this table. Example 1: ...
