Bitmask codeforces
WebNow let's iterate over all the pairs bi, bj and find in out data structure the value v closest to the value x = sa - sb + 2· (bi + bj) and update the answer by the value x - v . Required sum we can find using binary search by data structure (*map* in C++ has lower_bound function). C++ solution. Сложность: O( (n2 + m2)log(n + m)).

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 ... WebThere is just BFS.
