Algorithms: LCM and GCD
Least Common Multiple: lcm(a,b) = abs(a*b) / gcd(a,b) = abs(a) / gcd(a,b) * abs(b) Greatest common divisor: gcd(a,b) = gcd(b, a%b); Code: int gcd(int a, int b) { if (b == 0) return a; return gcd(b, a%b); }

Nice thing about the tutorial is that it populates a DB with data for you … Continue reading
Java: Reading/Writing File
Wrote a program that read a file for a company evaluation. I hastily put it together without looking too much at resources so it wasn’t the prettiest of things. Probably should’ve taken my time, so I will now and make … Continue reading
