LOOPS Time Limit: 15000/5000 MS (Java/Others) Memory Limit: 125536/65536 K (Java/Others) Total Submission But because of the plot of the Boss Incubator, she is trapped in a labyrinth called LOOPS. ? The planform of the LOOPS is a rectangle of R*C grids. At the beginning Homura is in the top left corner of the LOOPS ((1, 1)), and the exit of the labyrinth portal, your task is help poor Homura calculate the EXPECT magic power she need to escape from the LOOPS

进一步分析发现染色质环中有很大部分为promoter-enhancer loops, 这也解释了增强子对靶基因的调控机制,虽然增强子与靶基因线性距离很远,但是增强子与靶基因启动子位于一个染色质环上,空间距离近

For loops are mostcommonly used for iterating over the elements of an object (list, vector, etc.) for These following loops have the samebehavior: x<- c("a", "b", "c", "d") for(iin 1:4) { print(x[i]) } for loops can be nested. x<- matrix(1:6, 2, 3) for(iin seq_len(nrow(x))) { for(j in seq_len(ncol(x Nestingbeyond 2–3 levels is often very difficult to read/understand While While loops begin by testing can potentially result ininfinite loops if not written properly.
