The example below uses the input statement to read a value from a source (in this case the string 123) into a both a character destination and a numeric destination. data test; source = '123'; numeric_destination = input(source, best.); character_destination = input(source, $3.); run; ...

A common need for random numbers it to generate a number that is X% of some max value. this can be done by treating the result of NextDouble() as a percentage: var rnd = new Random(); var maxValue = 5000; var percentage = rnd.NextDouble(); var result = maxValue * percentage; //suppose NextDoub...

apcu_store can be used to store, apcu_fetch to retrieve values: $key = 'Hello'; $value = 'World'; apcu_store($key, $value); print(apcu_fetch('Hello')); // 'World'

The APCUIterator allows to iterate over entries in the cache: foreach (new APCUIterator() as $entry) { print_r($entry); } The iterator can be initialized with an optional regular expression to select only entries with matching keys: foreach (new APCUIterator($regex) as $entry) { pr...

Recursive mutex allows the same thread to recursively lock a resource - up to an unspecified limit. There are very few real-word justifications for this. Certain complex implementations might need to call an overloaded copy of a function without releasing the lock. std::atomic_int temp{0}; ...

First, we create an empty map, and insert some elements into it: Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<>(); Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>(); treeMap.put(10, "ten"); treeMap.put(4, "fou...

First, we create an empty set, and insert some elements into it: Java SE 7 TreeSet<Integer> treeSet = new TreeSet<>(); Java SE 7 TreeSet<Integer> treeSet = new TreeSet<Integer>(); treeSet.add(10); treeSet.add(4); treeSet.add(1); treeSet.add(12); Once we hav...

Since TreeMaps and TreeSets maintain keys/elements according to their natural ordering. Therefor TreeMap keys and TreeSet elements have to comparable to one another. Say we have a custom Person class: public class Person { private int id; private String firstName, lastName; priva...
