Above Average It is said that 90% of frosh expect to be above average in their class. You are to provide a reality check. The first line of standard input contains an integer C, the number of test cases. C data sets follow. Each data set begins with…

Average Precision (AP) @[ IoU=0.75 | area= all | maxDets=100 ] = 0.136 Average Precision (AP) @[ IoU=0.50:0.95 | area= small | maxDets=100 ] = 0.000 Average Precision (AP) @[ IoU=0.50:0.95 | area=medium | maxDets=100 ] = 0.198 Average Precision (AP)…

Given a stream of integers and a window size, calculate the moving average of all integers in the sliding window. For example,MovingAverage m = new MovingAverage(3);m.next(1) = 1m.next(10) = (1 + 10) / 2m.next(3) = (1 + 10 + 3) / 3m.next(5) = (10 + 3…

A non-empty zero-indexed array A consisting of N integers is given. A pair of integers (P, Q), such that 0 ≤ P < Q < N, is called a slice of array A (notice that the slice contains at least two elements). The average of a slice (P, Q) is the sum of…

在Linq中有一些这样的操作,根据集合计算某一单一值,比如集合的最大值,最小值,平均值等等.Linq中包含7种操作,这7种操作被称作聚合操作. 1.Count操作,计算序列中元素的个数,或者计算满足一定条件的元素的个数 2.Sum操作,计算序列中所有元素的值的总和 3.Max操作,计算序列中元素的最大值 4.Min操作,计算序列中元素的最小值 5.Average操作,计算序列中所有元素的平均值 6.Aggregate操作,对集合中的元素进行自定义的聚合计算 7.LongCount操作,计算集合中…

在Linux系统下面,有很多的命令可以查看系统的负载情况:比如top,uptime,w,示例如下: [wenchao.ren@l-cmsweb1.ops.cn1 ~]$ w 18:39:10 up 761 days, 13:59, 1 user, load average: 0.32, 0.45, 0.43 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT wenchao. pts/1 192.168.22.28 17:55 0.00s 0.03s 0.02s s…
