How do I use `break_` in the package “loops”?
问题 Looking into the package loops, I found it very interesting and could be useful. However, there's one part about the package that I don't understand: how am I supposed to use break_? Let's say I have a function get' :: IO (Maybe Int) , with which each call will return a number read from a file, and returns Nothing if the EOF is reached. I'm trying to construct a simple loop where I print each number and break upon EOF. Now, I know to loop indefinitely I can use forever : import Control.Monad

How to stop loop in cypress
问题 I have a loop checking 40 items. I want to stop my loop, when I am finding the first element, which > 0 This is my code var genArr = Array.from({ length: 40 }, (v, k) => k + 1); cy.wrap(genArr).each((index) => { cy.get('.list-item').eq(index - 1).find('.number') .invoke('text') .then(text => { const pendingCount = text; cy.get('.list-item').eq(index - 1).click(); cy.get('.list-table').find('.list-table-list-item') .should('have.length', pendingCount); if (text > 0) break }); }); }); But I

Go break和continue
1. break package main import ( "fmt" "math/rand" "time" ) func main() { //我们为了生成一个随机数，还需要个rand设置一个种子. //time.Now().Unix() : 返回一个从1970:01:01 的0时0分0秒到现在的秒数 //rand.Seed(time.Now().Unix()) //如何随机的生成1-100整数 //n := rand.Intn(100) + 1 // [0 100) //fmt.Println(n) //随机生成1-100的一个数，直到生成了99这个数，看看你一共用了几次 //分析思路： //编写一个无限循环的控制，然后不停的随机生成数，当生成了99时，就退出这个无限循环==》break var count int = 0 for { rand.Seed(time.Now().UnixNano()) n := rand.Intn(100) + 1 fmt.Println("n=", n) count++ if (n == 99) { break //表示跳出for循环 } } fmt.Println("生成 99 一共使用了 ", count) //这里演示一下指定标签的形式来使用 break lable2: for i := 0; i < 4; i++ { //lable1
R: Break for loop
问题 Can you confirm if the next break cancels the inner for loop? for (out in 1:n_old){ id_velho <- old_table_df$id[out] for (in in 1:n) { id_novo <- new_table_df$ID[in] if(id_velho==id_novo) { break }else if(in == n) { sold_df <- rbind(sold_df,old_table_df[out,]) } } } 回答1: Well your code is not reproducable so we never know for sure, but this is what help('break') says: break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop. So
Why does my break statement break “too far”?
问题 Here's a snippet of my code (based on this previous question): $rgdNames = (Get-AzureRmResourceGroupDeployment -ResourceGroupName "$azureResGrpName").DeploymentName $siblings = $rgdNames | Where-Object{$_ -match "^($hostname)(\d+)$" } if ($siblings) { # Make a list of all numbers in the list of hostnames $serials = @() foreach ($sibling in $siblings) { # $sibling -split ($sibling -split '\d+$') < split all digits from end, then strip off everything at the front # Then convert it to a number
Break and return inside multiple for-loops with conditional statement
问题 I have created a long code, consist of multiple lists inside for-loops. There are nothing wrong with calculation.It does obtain results as it is expected to. The code and construction of lists work fine. The problem is when it runs, I have defined a break when a certain condition is matched. But it does not break at first run, continues and run through all values within range function of first loop. I want to achieve to return a true value, when the condition is matched, and stops and will
