String Processing: Effective method to check string contains in Java
There are many applications (e.g. information retrieval, Natural Language processing) that require searching a large string for words, terms, or statements. The link below describe several methods to do that using C#.
In this assignment, you are expected to use a large input text file (of more than 3000 words). You will evaluate 3 different method, based on performance. All three methods should have the same signature
Public int NumberOfOccurrences (string inputfile, string word)
The output will be the number of time the word occur in the input file. Evaluate the three methods you selected based on performance. Test your code with 5 different test cases.
The Background:
How many of us C# programmers have had to check if a string is contained within another string? A simple match. We don't care how many times it may exist, we only want to know if it does.
There are numerous native C# methods for doing this: String.Contains(), String.IndexOf(), through Regex regular expressions, and similar options for those programmers obsessed with LINQ.
So that's when this curious consultant started wondering... what is the fastest way to test and see if a string is contained within another string?

Length of the con?dence interval
: i) Use the CLT to construct a con?dence interval for m with approximate con?dence coef?cient 1 - a; ii) What does this interval become if n = 100, s = 1 and a = 0.05? iii) Refer to part (i) and determine n so that the length of the con?dence interval..
