 ## What is it?
 
-Quantum Computing ABC is a tutorial example of writing a quantum computing program in Qiskit that searches through a random array of letters in order to find each letter in sequence for a target sentence, such as "Hello World!".
+Oracle is a tutorial example of writing a quantum computing program in Qiskit that searches through a random array of letters in order to find each letter in sequence for a target sentence, such as "Hello World!".
 
 The idea is similar to the traditional [ransom](https://leetcode.com/problems/ransom-note/) [note](https://dev.to/teekay/algorithms-problem-solving-ransom-note-2f5f) [problem](https://medium.com/@harycane/ransom-note-af09b54904d0). You're given a magazine of randomly cut out letters. The letters are strewn across a table in a random fashion. Your task is to find enough letters from the table in order to paste them together to produce the phrase "hello world".
 
 *Given two stings ransomNote and magazine, return true if ransomNote can be constructed from magazine and false otherwise. Each letter in magazine can only be used once in ransomNote.*

 ## Why would you use a quantum computer for this?
 
 To demonstrate the power of a quantum computer compared to a classical one, of course!

 While the example in this tutorial of selecting letters from an array of random elements is simplistic, it nevertheless demonstrates the speed-up in time complexity for searching and locating the desired elements.
