( 7446 ) D Letter Picking PROGRAMMING constructive algorithms dp games

B'Alice and Bob are playing a game. Initially, they are given a non-empty string s , consisting of lowercase Latin letters. The length of the string is even. Each player also has a string of their own, initially empty. Alice starts, then they alternate moves. In one move, a player takes either the first or the last letter of the string s , removes it from s and prepends (adds to the beginning) it to their own string. The game ends when the string s becomes empty. The winner is the player with a lexicographically smaller string. If the players ' strings are equal, then it 's a draw. A string a is lexicographically smaller than a string b if there exists such position i that a_j = b_j for all j < i and a_i < b_i . What is the result of the game if both players play optimally (e. xe2 x80 x89g. both players try to win; if they can 't, then try to draw)? The first line contains a single integer t ( 1 <= t <= 1000 ) -- the number of testcases. Each testcase consists of a single line -- a non-empty string s , consisting of lowercase Latin letters. The length of the string s is even. The total length of the strings over all testcases doesn 't exceed 2000 . For each testcase, print the result of the game if both players play optimally. If Alice wins, print "Alice". If Bob wins, print "Bob". If it 's a draw, print "Draw". One of the possible games Alice and Bob can play in the first testcase: Alice wins because "cef" < "ros". Neither of the players follows any strategy in this particular example game, so it doesn 't show that Alice wins if both play optimally. '...
