Use Big O notation, the primary tool for evaluating algorithms, to measure and articulate the efficiency of your code, and modify your algorithm to make it faster. Find out how your choice of arrays, linked lists, and hash tables can dramatically affect the code you write. Use recursion to solve tricky problems and create algorithms that run exponentially faster than the alternatives. Dig into advanced data structures such as binary trees and graphs to help scale specialized applications such as social networks and mapping software. You’ll even encounter a single keyword that can give your code a turbo boost. Jay Wengrow brings to this book the key teaching practices he developed as a web development bootcamp founder and educator.
Use these techniques today to make your code faster and more scalable."
involves solving polynomial equations in integers. It is well known that
a Diophantine equation is an equation with integer coefficient and
multiple variables ( 2) having integer solutions. There is no universal
method available to know whether a Diophantine equation has a
solutions or finding all solutions, if it exists. Proving that even simple
Diophantine equations have no solutions may require very
sophisticated methods and in such cases, a lot of deep and beautiful
mathematics get generated as a result. It is worth to observe that
Diophatine equations are rich in variety. A collection of special
Problems on biquadratic equations in 3,4,5 & 6 variables has been
treated in sections A to D respectively. Different sets of integer solutions
to each of the biquadratic diophatine equations are illustrated.
