My overly optimized solutions of Project Euler problems, focused on math algorithms and code efficiency

ID	Problem	Solution
1	Multiples of 3 and 5	C
2	Even Fibonacci numbers	C
3	Largest prime factor	C
4	Largest palindrome product	C
5	Smallest multiple	C
6	Sum square difference	C
7	10001st prime	C
8	Largest product in a series	C
9	Special Pythagorean triplet	C
10	Summation of primes	C
11	Largest product in a grid	C
12	Highly divisible triangular number	C
13	Large sum	C

Performance improvements and suggestions can be submitted here.

Every implementation must be:

• Parameterized: the problem inputs must be defined at compile time
• Deterministic: one input results in the same output every run
• Non-trivial: there can be no unexplained values in the code
• Efficient: every microsecond, bit and joule matters
