Are "while(true)" loops so bad?

I’ve been programming in Java for several years now, but I just recently returned to school to get a formal degree. I was quite surprised to learn that, on my last assignment, I lost points for using a loop like the one below.

do{ //get some input. //if the input meets my conditions, break; //Otherwise ask again. } while(true)

Now for my test I’m just scanning…

How to optimize for-comprehensions and loops in Scala?

So Scala is supposed to be as fast as Java. I’m revisiting some Project Euler problems in Scala that I originally tackled in Java. Specifically Problem 5: “What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?”

Here’s my Java solution, which takes 0.7 seconds to complete on my machine:

do-while loop in Python?

I need to emulate a do-while loop in a python. But, unfortunately, following straightforward code does not work:

l = [ 1, 2, 3 ] i = l.__iter__() s = None while True : if s : print s try : s = i.next() except StopIteration : break print "done"

Instead of “1,2,3,done” I have the following output:

[stdout:]1 [stdout:]2 [stdout:]3 None['Traceback (most recent call last):…

JavaScript – Are loops really faster in reverse…?

I’ve heard this quite a few times. Are JavaScript loops really faster when counting backward? If so, why? I’ve seen a few test suite examples showing that reversed loops are quicker, but I can’t find any explanation as to why!

I’m assuming it’s because the loop no longer has to evaluate a property each time it checks to see if it’s finished and…

Fixed Which is faster: while(1) or while(2)? #dev #it #asnwer

Which is faster: while(1) or while(2)?

This was an interview question asked by a senior manager.

Which is faster?

while(1) { // Some code }

or

while(2) { //Some code }

I said that both have the same execution speed, as the expression inside while should finally evaluate to true or false. In this case, both evaluate to true and there are no extra conditional instructions inside the whileconditi…
