java - for each loop with a second boolean parameter -

-
this question has answer here: java foreach condition 6 answers is there here know how this: boolean condition = true; for(int i=0; i<list.size() && condition; i++){ if (***) condition = false; } with each loop, that: boolean condition = true; for(string s : list && condition){ if (***) condition = false; } i know second loop not work, have same behaviour without using killing mortal ugly instruction "break". use break statement: for(string s: list) { if (....) { break; } } btw can kind of loop , imho preferable because more readable.

python - Neat way of popping key, value PAIR from dictionary? -

pop great little function that, when used on dictionaries (given known key) removes item key dictionary , returns corresponding value. if want key well? obviously, in simple cases this: pair = (key, some_dict.pop(key)) but if, say, wanted pop key-value pair lowest value, following above idea have this... pair = (min(some_dict, key=some.get), some_dict.pop(min(some_dict, key=some_dict.get))) ... hideous have operation twice (obviously store output min in variable, i'm still not happy that). question is: there elegant way this? missing obvious trick here? you can define dictionary object using python abc s provides infrastructure defining abstract base classes . , overload pop attribute of python dictionary objects based on need: from collections import mapping class mydict(mapping): def __init__(self, *args, **kwargs): self.update(dict(*args, **kwargs)) def __setitem__(self, key, item): self.__dict__[key] = item def __getit...

msp430 - Does MSP430G2553 takes care of interrupt re-entrancy or should I allocate stacks for each tasks in ISR? -

-
i @ present initializing stacks tasks need serviced upon receiving interrupt. example there 2 tasks gets called different periodicity, both tasks using same isr. task higher sample rate should interrupt lower sample rate task , enter same isr. @ present allocating stacks tasks , upon completion free stack memory. know if msp430 takes care of re-entrancy on it's own, not need create , delete stack, save , restore context. there's 1 (the current) hardware stack. so, in theory, long doesn't overflow, don't need create dedicated stacks , can handle interrupts on same stack.

i need count number of lines in string . line break can character can present in string (cr, lf or crlf). so possible new line chars: * \n * \r * \r\n for example, following input: this [\n] string [\r] has 4 [\r\n] lines the method should return 4 lines. know built in function, or implemented it? static int getlinecount(string input) { // provide implementation method? // want avoid string.split since performs bad } note: performance important me, because read large strings. thanks in advance. int count = 0; int len = input.length; for(int = 0; != len; ++i) switch(input[i]) { case '\r': ++count; if (i + 1 != len && input[i + 1] == '\n') ++i; break; case '\n': // uncomment below include other line break sequences // case '\u000a': // case '\v': // case '\f': // case '\u0085': // case '\u2028': // case '\u2029'...

c# - Improving performance of Dictionary using Arrays -

-
consider counting number of occurrences of particular letter in word. i came solution. string = "aabbcdc"; //output: a:2,b:2,c:2,d:1 var dict = new dictionary<char, int>(); foreach(var @char in a) { if(dict.containskey(@char)) dict[@char] = dict[@char] + 1; else dict.add(@char, 1); } foreach(var keyvaluepair in dict) console.writeline("letter = {0}, value = {1}", keyvaluepair.key, keyvaluepair.value); my friend argued solution can improved further using arrays better using above dictionary. i guess, dictionary lookup o(1) (arrays o(1), correct ?) . ideas how re-write program using arrays performs better? arrays o(1), correct arrays o(1) when accessing known offset. o(n) when have scan array find particular match. you not out-perform dictionary type of operation in general case. you can leverage accessing known offset caveat use arrays limited case. example, if know have input in range 'a'..'z', can ...

Amending .gitignore, removing files from git while keeping them locally -

all of developers have files should have been in .gitignore start of project, not. is there git command remove files git, while keeping them locally and keeping them locally on other developer machines, when git pull ? ideally should @ diff of .gitignore decide needs removed kept locally. at moment, considering following manual procedure: my machine: get full paths of files match new .gitignore , don't match old .gitignore add of files out-of-tree tar file git rm files commit , push origin master changes email tar file other developers every other developer's machine: git pull update .gitignore , remove local copies of files should ignored. untar tar file on top of local repo reinstate removed files this procedure has huge scope manual errors - there better way? i've looked at: remove file git without deleting them locally , remotely removing file versioning keeping locally? , http://gitready.com/intermediate/2009/02/18/temporar...
