split Algorithm
The split algorithm is a fundamental method in computer science and programming, which is widely used for dividing a larger data set or a string into smaller, more manageable parts. This algorithm is commonly employed in various programming languages such as Python, Java, and JavaScript, as well as in data processing and analysis tools. The primary purpose of the split algorithm is to parse, manipulate, and analyze data effectively by breaking it down into smaller, more targeted pieces. It can be particularly useful when working with strings, text files, or any complex data structures that need to be segregated based on specific delimiters, such as spaces, commas, or newline characters.
In the context of string manipulation, the split algorithm works by searching for a specified delimiter within a given input string and then separating the string into substrings at every occurrence of the delimiter. The resulting substrings are typically stored in an array or a list, which can then be processed or manipulated individually. For example, when analyzing a CSV (Comma Separated Values) file, the split algorithm can be used to divide each line of text into individual data fields based on the comma delimiter. Similarly, when processing a text document, the split algorithm can be used to break up the text into words or sentences based on spaces, punctuation marks, or other delimiters. This functionality allows programmers and data analysts to work with large data sets more efficiently and effectively, enabling them to extract valuable insights and perform complex tasks with relative ease.

Will split the string up into all the values separated by the separator (defaults to spaces)
>>> split("apple#banana#cherry#orange",separator='#')

>>> split("11/22/63",separator = '/')
