Quick Sort in Java Version 2

Here is the implementation of quick sort version 2 using Java as my programming language. Our program will ask the user how many items to be sorted and then it will ask the user to give a series of numbers and then it will be sorted using selection sort algorithm. I hope you will find my work useful.

Mathematics Tutorial Services in Bacolod City

Having problems following through classroom lectures in mathematics and science and appreciating mathematics and science at its basics? Do you need assistance in coping with the inherent challenges encountered with these subjects? You might just be in need of a follow up, or some more practice in solving problems in these areas. Then a one-on-one or guided practice might be the one for you. 

Mathematics is all about procedures and pattern(s) recognition in solving. If these procedures and patterns are understood, any mathematical procedure no matter how complex is made a lot easier and manageable as they may first appear at first reading. Scientific problems on the other hand need mathematical skills in applying the given information in the problem to appropriate formulas together with information like what is given and what is required in the problem.

Dr. Ma. Junallie F. Pomperada is a professor of the College of Engineering of the University of St. La Salle in the Chemical Engineering Department. Graduated from University of Negros Occidental-Recoletos and finished her Master of Engineering Major in Chemical Engineering from Central Philippine University. She finished her Doctor of Philosophy in Technology Management from Carlos Hilado Memorial State College.

Tutorial Services Offered:

Inorganic Chemistry, Analytical Chemistry, Thermodynamics, Algebra, Trigonometry, Differential and Integral Calculus, Differential Equations, Advanced Engineering Mathematics, Chemical Reaction Engineering, Process Control ad Unit Operations with Specialization in Distillation, Evaporation, Gas Absorption, Stripping, Extraction and Leaching.

She caters high school and college students who are is need proper guidance and direction in mathematics subjects. Her tutorial hourly rate's are very affordable it will discuss before the tutorial session.

Available time tutorial schedule will be on Saturday and Sunday only.

Big discounts for a group of students who will avail of her tutorial services.

For more information kindly contact her in her mobile number 0917 - 701 - 0825.
