( 7052 ) D Bicolored RBS PROGRAMMING constructive algorithms greedy 1500

B'A string is called bracket sequence if it does not contain any characters other than "(" and ")". A bracket sequence is called regular (shortly, RBS) if it is possible to obtain correct arithmetic expression by inserting characters "+" and "1" into this sequence. For example, "", "(())" and "()()" are RBS and ")(" and "(()" are not. We can see that each opening bracket in RBS is paired with some closing bracket, and, using this fact, we can define nesting depth of the RBS as maximum number of bracket pairs, such that the 2 -nd pair lies inside the 1 -st one, the 3 -rd one -- inside the 2 -nd one and so on. For example, nesting depth of "" is 0 , "()()()" is 1 and "()((())())" is 3 . Now, you are given RBS s of even length n . You should color each bracket of s into one of two colors: red or blue. Bracket sequence r , consisting only of red brackets, should be RBS, and bracket sequence, consisting only of blue brackets b , should be RBS. Any of them can be empty. You are not allowed to reorder characters in s , r or b . No brackets can be left uncolored. Among all possible variants you should choose one that minimizes maximum of r 's and b 's nesting depth. If there are multiple solutions you can print any of them. The first line contains an even integer n ( 2 <= n <= 2 cdot 10^5 ) -- the length of RBS s . The second line contains regular bracket sequence s ( |s| = n , s_i in { "(", ")" } ). Print single string t of length n consisting of "0"-s and "1"-s. If t_i is equal to 0 then character s_i belongs to RBS r , otherwise s_i belongs to b . In the first example one of optimal solutions is s = " color{blue}{()} ". r is empty and b = " () ". The answer is max(0, 1) = 1 . In the second example it 's optimal to make s = " color{red}{(} color{blue}{('...
