问题 I have a script which is like a whois database. This function returns site views and I want to echo between value. How can I echo and return one result? If the number is say 4000, it should return only 1k-10k Rows are like 1550330 1000000 The code: $siteTotalViews=1000000; if($siteTotalViews <= 100){ echo '0-100'; } if($siteTotalViews <= 1000){ echo '100-1k'; } if($siteTotalViews <= 10000){ echo '1k-10k'; } if($siteTotalViews <= 100000){ echo '10k-100k'; } if($siteTotalViews <= 1000000){ echo

Library for handling a List of Ranges

问题 I have to handle a list of timestamps ( Long ) in a Java 8 application: If a user adds a new range, it should be merged together with the other existing ranges, like in this pseudo code: rangeList = [100, 200], [300, 400], [500, 600], [700, 800] newRangeList = rangeList.add([150, 550]) println(newRangeList) // Expected output: [100, 600], [700, 800] I tried using a List of Google Guava Range class but merging together new timestamp ranges gets surprisingly complicated. Using the new

Form validation with Javascript - Field value must be between 2 specific numbers

问题 I have a form on a page. On the form there is a field named Birthyear. I need to figure out the following in javascript: When a value between 1900-2012 is entered into the field, the form are accepted. If value is not between 1900-2012, the Birthyear text box background color turn yellow. Does anyone know how to achieve this? My HTML is as follow: </head><body> <div id="div1"> <form name="myForm" action="demo_form.php" onsubmit="return validateForm()" method="post"> Username: <input type=

Number-system conversion in Matlab (from different system to decimal)

由 一笑奈何 提交于 2019-12-12 02:19:47
问题 Recently I've asked the help about converting numbers from decimal to other number-systems through MatLab. Now I need the help with the inverse operation. I wrote the program that converts from different systems to decimal and faced with the problem, when it comes to convert hex (base=16) to decimal. I need to make numbers like A=10, B=11 and so on. Tried to make switch-case, but it didn't help, even though it was working while converting from decimals clc clear all n = input('select number

Limit number of concurrent powershell jobs

问题 I know this question has been asked before and i have seen a couple of possible solutions, but i can't seem to be able to make any of them work for my script. My script is not a finished product, needs some cleaning up, but it definitely works at the moment. The basic function of the script is that it creates snapshots of virtual machines, and then clones them for backup purposes. Everything works as expected, but the problem is it brings my vcenter to it's knees because it is flooding it

Can we conclude a set might not be random by checking its subset?

由 為{幸葍}努か 提交于 2019-12-12 01:37:48
问题 Set A includes 1000 numbers. I checked that half of the numbers in this set are even. I extracted subset B from set A as follow: any number in set A which starts with 1 is also in set B. (All numbers in B start with 1). I checked that more than half of the numbers in set B are even. Half of the numbers in A are even so should we expect the same for B? But more than half of B are even. So can conclude that set A is not random? If 60% of B are even, can we still conclude A is not generated

Only add cells in column when the total of multiple other cells in that row equals 5

问题 So I am getting data fed into a spreadsheet on Google Sheets. I cannot edit that spreadsheet. I have an additional sheet in the document that totals up the columns in this sheet. The sheet received info such as: A B C D This info is not actually in the sheet |------------| \/ \/ | 4 1 0 0 | <-- Valid | 3 1 1 0 | <-- Valid | 3 1 0 2 | <-- Invalid | 3 0 1 1 | <-- Valid |------------| The total of each individual row should be 5, but I do not currently have a way of validating this in the form

C++: a scalable number class - bitset<1>* or unsigned char*

由 試著忘記壹切 提交于 2019-12-12 01:06:53
问题 I'm planning on creating a number class. The purpose is to hold any amount of numbers without worrying about getting too much (like with int, or long). But at the same time not USING too much. For example: If I have data that only really needs 1-10, I don't need a int (4 bytes), a short(2 bytes) or even a char(1 byte). So why allocate so much? If i want to hold data that requires an extremely large amount (only integers in this scenario) like past the billions, I cannot. My goal is to create

Java integer part padding

由 夙愿已清 提交于 2019-12-12 00:52:36
问题 Sorry I was initially wanting to do it in php PHP integer part padding, but realised I will do it in Java in another part of code So I need to format numbers with the integer part at least 2 chars 2.11 -> 02.11 22.11 -> 22.11 222.11 -> 222.11 2.1111121 -> 02.1111121 double x=2.11; System.out.println(String.format("%08.5f", x)); could do it, but it's annoying the right trailing zeros, I would like to have an arbitrary large floating part String.format("%02d%s", (int) x, String.valueOf(x-(int)

What data type can be used to hold the value of the factorial of 100,000,000?

由 拜拜、爱过 提交于 2019-12-11 23:19:04
问题 Data type to hold a very large number say 1000 or more digits? I need to find the factorial of a large number say 100000000. My factorial program works nice for a smaller number. long factorial(int x) { long fact=1; if(x<0) { System.out.println("Incorrect input, enter a positive number"); fact=0; } if(x==0) fact=1; if(x>0) { fact=x; fact=fact*factorial(x-1); } return fact; } 回答1: You need a BigInteger . It can hold an arbitrarily large number. But in your case 100000000! is such a huge number
