contains elements hashmap in arraylist java -


i have hashmap<integer,arraylist<integer>> h , arraylist<integer> l want test if first element in arraylist similar @ first value in hashmap want

 (entry<integer, arraylist<integer>> e : hmm.entryset()) {         integer key1 = e.getkey();          list<integer> valeur = e.getvalue();         int count = 0;         int k = 0;         //integer temp : listoperateur;          if (valeur.contains(listoperateur)) {             count++;           }          sim.put(key1, count);         k++;      }

this code can you

    iterator i1 = listoperateur.iterator();     (map.entry<integer, arraylist<integer>> e : hmm.entryset()) {        //if (e.getvalue() != null) {             count = 0;             //you can move part method avoid deep nested code             (integer mapvalue : e.getvalue()) {                 // (integer listvalue : listoperateur) {                 if (mapvalue.equals(listoperateur.get(k))) {                     count++;                     //  }                 }             }             sim.put(e.getkey(), count);             k++;       //  }     }

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

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
