WebIntroduction. Let's learn bitwise operations that are useful in Competitive Programming. Prerequisite is knowing the binary system. For example, the following must be clear for you already. 13 = 1 ⋅ 8 + 1 ⋅ 4 + 0 ⋅ 2 + 1 ⋅ 1 = 1101 ( 2) = 00001101 ( 2) Keep in mind that we can pad a number with leading zeros to get the length equal to ...

WebAlgorithm is simple: solve(set, set_size, val) count = 0 for x = 0 to power(2, set_size) sum = 0 for k = 0 to set_size if kth bit is set in x sum = sum + set[k] if sum >= val count = count + 1 return count. To iterate over all the subsets we are going to each number from 0 to 2 set_size -1. The above problem simply uses bitmask and complexity ...

WebNote that the number of different colours is 60, so we can store the set of colours just as mask of binary bits in 64-bit type (*long long* in C++, long in Java). Let's build the segment tree over the permutation which supports two operations: paint subsegment by some colour and find the mask of colours of some segment.
