Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Agree.
v[i+2] will be out of bounds when i >= v.size() - 2;
for loop condition is i<v.size(); I wonder how this code even passed all the tests!???
x |= 1 << (board[row][col] - 1);
when board[row][col] == 0 you are shifting left by -1. This is UB
Sorry sir, i don't think this is best practrice code. You are using loop and this wierd if() at the end...
Why not just format each component once and then just add them? Look at my solution and say what you think.
+1 Clever for recursion
-1 Best practices for the same reason )))
Why don't you check if i is prime or not before n % i == 0 check?
Kata says: "Given a positive number n > 1 find the prime factor decomposition of n."
So i must be prime... Am i right?
Why this terribly slow solution with unordered_map got so many votes?
Template overuse detected!
Also this solution is not so good because of 55
op2 for jnz could be reg. It is not guaranteed to be a constant.
quote from description:"jnz x y - jumps to an instruction y steps away (positive means forward, negative means backward, y can be a register or a constant), but only if x (a constant or a register) is not zero"
