Problem Statement

More investigation of continued fractions and the continued fraction representation of square roots.

Blog post: Computing square roots using continued fractions: https://charlesreid1.com:3000/cs/euler/src/master/scratch/Round2_050-070/063/Problem063.java

Solution Technique

The blog post linked above contains some of the code used to solve this problem, but it basically boils down to implementing the recurrence relation formula that we already saw in Project Euler/57, with various initial conditions.

Code

ContinuedFractionBig.java defines the ContinuedFractionBig class: https://charlesreid1.com:3000/cs/euler/src/master/scratch/Round2_050-070/064/ContinuedFractionBig.java

Problem064.java uses the ContinuedFractionBig class to solve the problem: https://charlesreid1.com:3000/cs/euler/src/master/scratch/Round2_050-070/064/Problem064.java
