Angular 2 CLI environment set up -


i want set development, test(qa) , prod environment angular 2 project. while going qa env set ng build --environment=qa

i getting below error

cannot read property 'length' of undefined @ createsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:15457:109) @ parsesourcefileworker (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:15389:26) @ object.parsesourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:15338:26) @ object.createsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:15192:29) @ virtualfilestats.getsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\@ngtools\webpack\src\compiler_host.js:66:35) @ webpackcompilerhost.getsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\@ngtools\webpack\src\compiler_host.js:213:38) @ findsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67909:29) @ processimportedmodules (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:68056:25) @ findsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67937:17) @ processsourcefile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67840:27) @ processrootfile (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67728:13) @ d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67018:60 @ object.foreach (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:1449:30) @ object.createprogram (d:\ecc web\ecc web\working\8-aug\node_modules\typescript\lib\typescript.js:67018:16) @ aotplugin._setupoptions (d:\ecc web\ecc web\working\8-aug\node_modules\@ngtools\webpack\src\plugin.js:129:28) @ new aotplugin (d:\ecc web\ecc web\working\8-aug\node_modules\@ngtools\webpack\src\plugin.js:26:14)

below code environment set in angular-cli.json

"environments": {         "dev": "environments/environment.ts",         "prod": "environments/environment.prod.ts",         "qa": "environments/environment.qa.ts"       }

in environments/environment.qa.ts

export const environment = {     production: false   };

typescript wants read source file doesn't exist. stack trace doesn't mention name of missing file, can editing file node_modules\typescript\lib\typescript.js - add log statement console.log(filename); @ beginning of createsourcefile method , run build command again. last filename before error should 1 causing problem.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
