WebErrichto's blog. Bitwise operations 2 — popcount & bitsets. Part 1 ( link) introduces basic bitwise operations. This is part 2 and it's mainly about (in)famous bitsets and example problems. Also, see links to very useful advanced stuff at the bottom. EDIT: here's video version of this blog (on my Youtube channel). WebFor example, suppose in a set of 5 objects, we have picked the 1st , 3rd , and 4th object. The bitmask to represent this in binary is 01101 or 13 in decimal (in the notes, the 1 st bit will always be the least significant bit …

WebMar 30, 2024 · The above problem is the well-known Travelling Salesman Problem. The first part is to calculate the minimum distance between the two cells. We can do it by simply using a BFS as all the distances are unit distance. To optimize our solution we will be pre-calculating the distances taking the initial location and the location of the houses as the ...

WebApr 9, 2024 · Bitmask DP is a type of dynamic programming that uses bitmasks, in order to keep track of our current state in a problem. A bitmask is nothing more than a number that defines which bits are on and off, or a binary string representation of the number.
