Provide tags and a correct Python 3 solution for this coding contest problem. Polycarp has n coins, the value of the i-th coin is a_i. It is guaranteed that all the values are integer powers of 2 (i.e. a_i = 2^d for some non-negative integer number d). Polycarp wants to know answers on q queries. The j-th query is de...
