![]() Returns the number of values in the collection. Returns a shuffled copy of the collection. ![]() Returns the index at which the value should be inserted into the sorted collection. SortedIndex _::sortedIndex(collection, value, ) The following lines are identical ways to double a list of numbers. Underscore.php works in both object-oriented and static styles. For consistency and memorability, _ has been chosen for both the function and class name. The previous declaration of _ in PHP forces Underscore.php to use another name. In many PHP installations, _() already exists as an alias to gettext(). Some functions were not ported from Underscore.js to Underscore.php for technical reasons or because they weren't applicable to PHP. Object-Oriented and Static Styles Collections Underscore.php is hosted on GitHub and open sourced under the MIT license. Underscore.php requires PHP 5.3 or greater. In addition to porting Underscore's functionality, Underscore.php includes matching unit tests. Otherwise, increment count by 1 and update the value of index to index + 1.Ĥ-Extract the substring from test_str starting from the index position to the end of the string using is a PHP port of the popular Underscore.js library. ![]() If the find() method returns -1, exit the loop.Ĭ. Find the index of the K character in test_str starting from the index position using the find() method.ī. Method #5: Using the string method find() and string slicing.ġ-Initialize the input string test_str, the character to find K, and the Nth occurrence N.Ģ-Initialize a variable index to 0 and a variable count to 0.Ī. This is because the algorithm only stores the index of Nth occurrence of K and the extracted substring in memory, and these variables have constant size regardless of the input size. The loop runs N times and, in each iteration, it searches for the next occurrence of K in the substring of test_str, which has an average length of K.Īuxiliary Space: O(1), which means it uses a constant amount of extra memory to execute. Time Complexity: O(N*K), where N is the value of N and K is the average length of the substring between two occurrences of K in the test_str.
