Inserting and Moving elements inside Ruby Array

By -
Here's is an array with 5 elements 2.1.2 :001 > arr = ["a", "b", "c", "d", "e"] => ["a", "b", "c", "d", "e"] Lets look at few different cases Insert a new element at starting position Using unshift 2.1.2 :002 > arr.unshift("f") => ["f", "a", "b", "c", "d", "e"] Using insert 2.1.2 :005 > arr.insert(0, "f") => ["f", "a", "b", "c", "d", "e"] In the above example 0 is the position(index) Move existing element from one position to another The element in this case is "e" Using uniq to show only unique elements 2.1.2 :009 > arr.insert(0, "e").uniq => ["e", "a", "b", "c", "d"] With uniq we are only showing unique records but the element is listed ...

Remove duplicates from a JavaScript Array

By -
In JavaScript, you may combine the indexOf() method and the filter() method to get rid of duplicates from an array function removeDuplicates(arr) { return arr.filter((el, index) => arr.indexOf(el) === index); } let numbers = [1, 2, 3, 3, 4, 4, 5]; let uniqueNumbers = removeDuplicates(numbers); console.log(uniqueNumbers); // [1, 2, 3, 4, 5] The removeDuplicates() function in this code accepts an array as an argument and produces a new array that is empty of duplicates. This is accomplished by creating a new array with the filter() method that only contains elements that are unique within the original array. A callback function is provided as an argument to the filter() method, which is used to filter each element of the array. By comparing the current element's index to the output of executing indexOf() on the original array, the callback function determines if the current element exists only once in the array. The element is added to the new array if the two indices a...

Overview of Natural Language Processing (NLP)

By -
The study of the interaction between computers and human (natural) languages is known as natural language processing (NLP), and it is a subfield of computer science, artificial intelligence, and linguistics. Speech recognition systems, automatic translation tools, and virtual assistants are just a few examples of the applications that can grasp, interpret, and synthesise human language thanks to the employment of NLP technologies. Human language is ambiguous and context-dependent, which makes it challenging for computers to effectively interpret and understand. This is one of the main issues of NLP. NLP algorithms and models use methods like statistical analysis, machine learning, and deep learning to analyse and comprehend the structure and meaning of natural language in order to get around this problem. Language translation is one of the main uses of NLP, enabling people to communicate with one another in many languages. Text can be automatically translated from one language to anoth...
