loops

问题 In bash I need to run a script that loops from i=1 to i=99999999 but it always run out of memory. Is there any workaround? or is there a max value for i? first=1 last=99999999 randomString="CXCXQOOPSOIS" for val in $( seq $first $last ) do padVal=$( printf "%010d\n" $val ) hash=$( echo -n $randomString$padVal | md5sum ) if [[ "$hash" =~ ^000000) ]]; then echo "Number: $val" >> log_000000 echo "$val added to log - please check." fi done 回答1: bash provides C-like syntax for loop: first=1 last

问题 How can I iterate each $TwitterStatuses element/item/object? (And, how do I inspect each "status"?) Import-Module PSTwitterAPI Set-TwitterOAuthSettings -ApiKey $env:ApiKey -ApiSecret $env:ApiSecret -AccessToken $env:AccessToken -AccessTokenSecret $env:AccessTokenSecret #Get-TwitterUsers_Lookup -screen_name 'mkellerman' $TwitterStatuses = Get-TwitterStatuses_UserTimeline -screen_name 'mkellerman' #$TwitterStatuses = [array]Get-TwitterStatuses_UserTimeline -screen_name 'mkellerman' Foreach (

问题 I am writing a program to write text to a file based on user input, stopping when a blank line is entered, I.E. when hasNextLine is false. However, after running the program the file contains thousands of instances of the same line of input, which continues to grow until I kill the program. Could someone advise me on where I am going wrong please? import java.util.Scanner; import java.io.FileNotFoundException; import java.io.PrintWriter;; public class Lab_Week8_WriteAStory { public static

问题 Trying to make a for loop that has the HHMM outputted in a data-time HTML field. I currently have: for ($i = 1; $i <= 20; ++$i) { echo '<div class="mb-timer-hour"><div class="mb-timer-half" data-time="0830"></div></div>'; } Except this outputs data-time="0830" every time. I then tried $h = 30; $h + 30 but this then goes: 0800, 0830, 0860, 0890, ... Is it possible to loop 0800, 0830, 0900, 0930, ... ? The start time and end times are user variables which is why I haven't hard coded an array.

问题 I am writing a macro that splits out data to another sheet after comparing values in column A to a set variable. Column A has all Work Order numbers. I need the macro to create a new sheet for each new work order, and copy all lines to that sheet. It needs to name the sheet with a concatenation of the value found in column A and Column B, and then copy all rows associated with that Work Order to the new sheet. The prefix is the Work Order. Prefix 12581 should get its own sheet, named 12581-4,

问题 I'm trying to iterate a for loop many times but it's only printing out once. sample_gamma <- function(alpha, beta, n, iter) { mean_s = c() mean_sd = c() for(i in 1:iter){ a = rgamma(n, shape = alpha, scale = 1/beta) return(c(mean(a), sd(a))) } 回答1: i think you are looking for this sample_gamma <- function(alpha, beta, n, iter) { mean_s = c() mean_sd = c() for(i in 1:iter){ a = rgamma(n, shape = alpha, scale = 1/beta) print(c(mean(a), sd(a))) } } 来源： https://stackoverflow.com/questions

问题 I'm very new to C and I'm trying to write a program that checks if a string contains any uppercase letters, and if it does, prints them out. I'm using https://www.onlinegdb.com/online_c_compiler# as my compiler (cause I don't have access to my personal computer right now) and after a test run, the results are (p.s. I know gets isn't safe): main.c:16:5: warning: ‘gets’ is deprecated [-Wdeprecated-declarations] /usr/include/stdio.h:638:14: note: declared here main.c:(.text+0x26): warning: the

问题 This is currently the code that I am using. I embedded the code inside a change event when a cell within a range changes. But, every time I do change a cell within the range the entire loop starts from the top of the row and inserts the data in the destination cells repetitively. Is there a way that the loop doesn't post the data that is already at the destination? I guess I need the loop not to loop a cell that it already looped on the INFO INPUT sheet. The change event triggers the macro
