k 是一个定值,所以我们可以使用一个 map 记录每个数字出现的次数,在遍历 nums 的时候计算满足题意的数对个数,并更新 map 。 遍历 nums 中的数字 num ,让其作为数对的 nums[j] ,那么 nums[i] 的取值只有 num - k 和 num + k。 将这两个数字的出现次数计入答案,然后更新 num 的出现次数。 时间复杂度...

We examine the feasibility, benefits, and obstacles associated with this approach. Given an Initial Boundary Value Problem (IBVP) and a finite difference method, we directly compute stencil coefficients and assign them to the kernel of a convolution layer, a common component used in ML. The ...
Difference between instanceof vs getClass() in Java Before jumping into the equals() method and how they break the symmetry clause let's verify the behavior getClass() and instanceof operator in Java. Consider the below code, what do you think it will return, true or false?
.filter(pl.col("Category").is_in(["A","B"])) ) If this expression is eagerly executed, thegroupbyoperation will be unnecessarily performed for the whole DataFrame, and then filtered byCategory. With lazy execution, the DataFrame can be filtered andgroupbyperformed on only the required data...
