pseudocode - What's the difference between pseudo code and Algorithm? -


what's difference between pseudo code , algorithm? can give me example? tried search online i'm still confused algorithm. pseudo code written in words, that. fail understand algorithm. there difference between alogrithm , code?

an algorithm sequence of steps no fixed representation. can described in high-level description, pseudocode or code in language.

more generically, program written in language, pseudocode or concrete sequence of steps can considered algorithm.

there's no fixed format pseudocode - can similar language or combination of languages, or can natural language description of algorithm.

as example, insertion sort algorithm.

a high-level description is:

keep sorted list starts off empty. each element in original list, insert correct position in sorted list. return sorted list.

a pseudo-code representation (as per wikipedia) is:

for ← 1 length(a)     x ← a[i]     j ←     while j > 0 , a[j-1] > x         a[j] ← a[j-1]         j ← j - 1     a[j] ← x

and can write in java, c++, c or other language.

these representations of insertion sort algorithm.

* - there few variants of insertion sort, , these can all, in own right, considered algorithms, , there's ambiguity in above high-level description (which can lead different variants), let's ignore these aspects now.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
