• Big O Complexity of a method

  - by timeNomad

  I have this method: public static int what(String str, char start, char end) { int count=0; for(int i=0;i<str.length(); i++) { if(str.charAt(i) == start) { for(int j=i+1;j<str.length(); j++) { if(str.charAt(j) == end) count++; } } } return count; } What I need to find is: 1) What is it doing? Answer: counting the total number of end occurrences after EACH (or is it? Not specified in the assignment, point 3 depends on this) start. 2) What is its complexity? Answer: the first loops iterates over the string completely, so it's at least O(n), the second loop executes only if start char is found and even then partially (index at which start was found + 1). Although, big O is all about worst case no? So in the worst case, start is the 1st char & the inner iteration iterates over the string n-1 times, the -1 is a constant so it's n. But, the inner loop won't be executed every outer iteration pass, statistically, but since big O is about worst case, is it correct to say the complexity of it is O(n^2)? Ignoring any constants and the fact that in 99.99% of times the inner loop won't execute every outer loop pass. 3) Rewrite it so that complexity is lower. What I'm not sure of is whether start occurs at most once or more, if once at most, then method can be rewritten using one loop (having a flag indicating whether start has been encountered and from there on incrementing count at each end occurrence), yielding a complexity of O(n). In case though, that start can appear multiple times, which most likely it is, because assignment is of a Java course and I don't think they would make such ambiguity. Solving, in this case, is not possible using one loop... WAIT! Yes it is..! Just have a variable, say, inc to be incremented each time start is encountered & used to increment count each time end is encountered after the 1st start was found: inc = 0, count = 0 if (current char == start) inc++ if (inc > 0 && current char == end) count += inc This would also yield a complexity of O(n)? Because there is only 1 loop. Yes I realize I wrote a lot hehe, but what I also realized is that I understand a lot better by forming my thoughts into words...

• ASP.NET button click event still firing even through custom server-side validation fails

  - by Josh

  I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards. Any ideas on why this is?

• Rails 3 and encrypted cookies with IE9

  - by user1832686

  I am using encrypted cookies to pass data to my rails app. Once these cookies get set, they are being passed just fine to Chrome, Firefox, Safari (iOS and OSX version), etc. However, the cookie isn't being passed back on Win7/IE9.

E.g: cookies.permanent.encrypted[:some_data] = object.some_data Any ideas about what's going on?

• Python: Container object that preserves ordering and enforces uniqueness?

  - by Infinity

  Is there anything like this in the standard library? I've looked but haven't found it. It needs to be like a list (preserves order) but also like a set (elements can only appear once). So if you give it ['a', 'b', 'a'] it should return ['a', 'b'] Thanks!

• High accuracy cpu timers

  - by John Robertson

  An expert in highly optimized code once told me that an important part of his strategy was the availability of extremely high performance timers on the CPU. Does anyone know what those are and how one can access them to test various code optimizations? While I am interested regardless, I also wanted to ask whether it is possible to access them from something higher than assembly (or with only a little assembly) via visual studio C++?

  I have a form in Swing with a lot of textfields receiving data. The idea is when a button is clicked, the app gathers all the data from the textfields at once. Do you know a good practice for this? Or is it necessary to gather the data textfield by textfield?

• Dropdown menu (SELECT element) not losing focus correctly in IE6

  - by devils-avacado

  Example (load in IE6): http://jsbin.com/uheco/14 In IE6, if the user clicks on a SELECT and does not click any OPTION but instead clicks somewhere else on the page outside the SELECT, the SELECT still has focus. I expected the SELECT to lose focus when I clicked once outside of it (such as in IEs 7 & 8).

• Python: read streaming input from subprocess.communicate()

  - by Heinrich Schmetterling

  I'm using Python's subprocess.communicate() to read stdout from a process that runs for about a minute. How can I print out each line of that process's stdout in a streaming fashion, so that I can see the output as it's generated, but still block on the process terminating before continuing? subprocess.communicate() appears to give all the output at once.

• Find current value of a variable that depreciates linearly over time

  - by Hugi

  Let's say we have an empty bathtub. We've lost the plug, so once water is added it will drain away at a constant rate of 2 liters pr. minute. We add water to the tub in increments. 60 liters at 10:51, 30 liters at 11:54 and 50 liters at 13:18. So, the question is: How can I find out how much water is in the bathtub at any given time?

• Cosmic Rays: what is the probability they will affect a program?

  Once again I was in a design review, and encountered the claim that the probability of a particular scenario was "less than the risk of cosmic rays" affecting the program, and it occurred to me that I didn't have the faintest idea what that probability is. What is the probability of a cosmic ray hitting a computer and affecting the execution of the program?
