# ProjectEuler-Problems

1. Longest Collatz Sequence

2. Largest Prime Factor

3. Prime Summations

4. XORDecryption

5. Multiples of 3 and 5

6. Special Pythagorean triplet

7. Summation Of Primes (Used Seive of Eratosthenes)

8. Digit Factorial Chain (Finally Long wait over Solved it memoization DP)(Planning to rewrite it in Java)

9. Maximum Path Sum 1 (Took Help From Discussion)(Very Important and Interesting Problem uses concept of BFS)

10. Highly divisible triangular number (Trick to this problem was to find the number of factors a number has we have to multiply the powers of its prime factors + 1 e.g. (p+1)(q+1)(r+1))

11. Pandigital Prime (Generated permuations of digits!!!! :))

12. Largest product in a grid

13. Coded triangle numbers

14. Pentagon Numbers (use property of pentagonal numbers i.e. n=(sqrt(1+24*x)+1)/6 is natural number)

15. Truncatable primes (very un-optimized NEED TO OPTIMIZE SOLUTION)

16. Non-abundant sums

17. N-Digit Fibonacci Number

18. Goldbach's other conjecture

19. Amicable Numbers

20. Prime power triples

21. Circular Primes

22. Quadratic Primes

23. Lexicographic Permutations

24. Lattice Paths
