std::array being a STL container, can use range-based for loop similar to other containers like vector int main() { std::array<int, 3> arr = { 1, 2, 3 }; for (auto i : arr) cout << i << '\n'; }

As of Ruby 2.4.0, you can start an interactive IRB session inside any Ruby script using these lines: require 'irb' binding.irb This will start an IBR REPL where you will have the expected value for self and you will be able to access all local variables and instance variables that are in scope....

The basic use of fit is best explained by a simple example: f(x) = a + b*x + c*x**2 fit [-234:320][0:200] f(x) ’measured.dat’ using 1:2 skip 4 via a,b,c plot ’measured.dat’ u 1:2, f(x) Ranges may be specified to filter the data used in fitting. Out-of-range data points are ignored. (T. W...

Before starting with deletion I just want to put some lights on what is a Binary search tree(BST), Each node in a BST can have maximum of two nodes(left and right child).The left sub-tree of a node has a key less than or equal to its parent node's key. The right sub-tree of a node has a key greater ...

:help [subject] attempts to find the "best" match for the argument you supply. The argument "can include wildcards like *, ? and [a-z] (any letter). You can additionally use Vim's command-line completion with CTRL+D: :help spli<Ctrl-D> will display a list of help topics matchi...

For example if the input is: Output should be false: As 4 in the left sub-tree is greater than the root value(3) If the input is: Output should be true

struct tree{ int a; tree* right; tree* left; }; tree* root=NULL; void insert(tree*& in, int b){ if(in){ if(in->a<b) insert(in->right,b); else if(in->a>b) insert(in->left,b); ...

The Search API provides access to recent tweets*. This is as opposed to the Stream API, which provides search results in real-time. <example> *Note that "the Search API is focused on relevance and not completeness" - Twitter Search API

There are several ways to search a given value in std::set or in std::multiset: To get the iterator of the first occurrence of a key, the find() function can be used. It returns end() if the key does not exist. std::set<int> sut; sut.insert(10); sut.insert(15); sut.insert(22); ...

Generate a random letter between a and z by using the Next() overload for a given range of numbers, then converting the resulting int to a char Random rnd = new Random(); char randomChar = (char)rnd.Next('a','z'); //'a' and 'z' are interpreted as ints for parameters for Next()

/** * NetSuite will loop through each record in your search * and pass the record type and id for deletion * Try / Catch is useful if you wish to handle potential errors */ function MassDelete(record_type, record_id) { try { nlapiDeleteRecord(record_type, record_id...

In a basic implementation the task module must define a run/1 function that takes a list of arguments. E.g. def run(args) do ... end defmodule Mix.Tasks.Example_Task do use Mix.Task @shortdoc "Example_Task prints hello + its arguments" def run(args) do IO.puts "Hello ...

Sometimes, you need to output to more than one index in ElasticSearch, or have a custom mapping you want to apply to new indices as they roll in. There are two ways to apply a custom mapping.

y ~ . : Here . is interpreted as all variables except y in the data frame used in fitting the model. It is equivalent to the linear combinations of predictor variables. For example y ~ var1 + var2 + var3+...+var15 y ~ . ^ 2 will give all linear (main effects) and second order interaction terms of t...
