SeaMoney has a feature to transfer money between users. Let's imagine a simple scenario. N usernames-consisting of lowercase Latin characters-each starts with a balance b. Amongst them, T transactions happened, where user ua transfers x amount of money to up. If x is larger than the ua's balance when the transaction happens, the transaction is automatically rejected. Output the final balance of each user. Input The first line contains two numbers N and T (1 < N,T < 1000). Each of the next N following lines contain username u; (1 < |u;| < 10) and integer b; (1 < b; < 10°), denoting the balance of user u;. Following that are T lines, each containing two usernames ua and uz (ua # Ub) followed by an integer x (1 < x < 10º), denoting the amount of money transferred from ua to up . Output Output the balance of all users in alphabetical order.
