hash

问题 After checking this Ruby convert array to nested hash and other sites I am not able to achieve the following convertion: I have this: {"a"=>"text"} {"b"=>{"x"=>"hola"}} {"b"=>{"y"=>"pto"} } and I want to obtain: {"a"=>text, b=>{"x" => "hola", "y" => "pto" } } Until now the code seems like this: tm =[[["a"],"text"],[["b","x"],"hola"],[["b","y"],"pto"]] q = {} tm.each do |l| q = l[0].reverse.inject(l[1]) { |p, n| { n => p } } i += 1 end I tried with merge , but it overwrites the keys!. I tried

问题 I am trying to get the value of the key by matching key name(ignoring the white and character case). Code : $tagHash = (Get-AzResourceGroup -Name "twmstgmsnp").Tags Write-Host "Resource Group tags key : " $tagHash.Keys Write-Host "Resource Group tags value : " $tagHash.Values $ownervalue = $tagHash.GetEnumerator() | ? {($_.Key).ToString().Replace(' ','') -eq 'CreatedBy'} | % Value Write-Host "Resource Group CREATEDBY tag : " $ownervalue Result : Resource Group tags key : PURPOSE Created By

问题 My original Text : "sanjay" SHA-1 Text : "25ecbcb559d14a98e4665d6830ac5c99991d7c25" Now how can i get original value - "sanjay" from this hash value ? is there any code or algorithm or method? 回答1: No. That's usually the point -- the process of hashing is normally one-way. This is especially important for hashes designed for passwords or cryptology -- which differ from hashes designed, for say, hash-maps. Also, with an unbounded input length, there is an infinite amount of values which result

问题 I'm trying get a subset of keys for each hash in an array. The hashes are actually much larger, but I figured this is easier to understand: [ { id:2, start: "3:30", break: 30, num_attendees: 14 }, { id: 3, start: "3: 40", break: 40, num_attendees: 4 }, { id: 4, start: "4: 40", break: 10, num_attendees: 40 } ] I want to get only the id and start values. I've tried: return_keys = ['id','start'] return_array = events.select{|key,val| key.to_s.in? return_keys} but this returns an empty array. 回答1

问题 I'm building a batch program integrating fciv, certutil and powershell for compatibility on hashing folders on legacy systems. I ran into a bug where fciv will not hash some files while doing recurse hashings, below is a snippet of the code used. "%workingDir%fciv.exe" "\\?\%targetDir%" -%hashType% -r For example, i am scanning C:\Windows\System32\wbem\en-GB , results from FCIV shows that it scanned 67 files, while CertUtil and Powershell methods scanned 166 files. I tried to scan individual

This is the raw JSON object: {"num":11,"content":"puss\n","percentage":0} I want to replace 11 with 12 , namely change the value of "num". {"num":12,"content":"puss\n","percentage":0} Please describe it in Ruby language. 回答1: Convert the raw json string into hash object using JSON#parse. Change the hash object as you want. Then convert it back to json string using JSON#dump: require

问题 I want to hash small dictionary ("dictionaries/small"). Main file compiles correctly, but at runtime it produces "Segmentation fault" message with function insert() (specifically something wrong with malloc() , but I don`t know what). HASH.c #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #include <ctype.h> #include <string.h> typedef struct node { char* name; struct node* next; } node; node* first[26] = {NULL}; int hash(const char* buffer) { return tolower(buffer[0]) - 'a'; }
