Output Print thek-th largest number in an × mmultiplication table. 二分答案,每次判断当前数多大的函数是O(n),二分次数应为O(lognm)次,所以总共O(nlongnm) ps: Python跑的好慢啊。。看来c++要跑150ms的Python就得超时 View Code
Let's say you want to help a child to better understand math concepts by creating a multiplication table. Enter numbers 1-10 in cells A2 to A11 and again in cells B1 to K1. Enter this formula in cell B2. The $ locks the value for the header row and the formula multiplies it by th...
