AT_abc467_b.Keep the Change

Takahashi made purchases at $N$ stores. Initially, he had $10000$ yen.
At the $i$-th store, he bought an item worth $A_i$ yen and paid $B_i$ yen. Here, $A_i \leq B_i$ holds. If $S_i =$ keep, he did not receive the change, and if $S_i =$ take, he received the change.
Find the amount of money he lost compared to the case where he received the change at every store. To be precise,

• let $X$ yen be Takahashi's final amount of money, and
• let $Y$ yen be Takahashi's final amount of money in the case where he received the change at every store.

Find $Y - X$.

高桥在 $N$ 家商店进行了购物。最初，他有 $10000$ 日元。
在第 $i$ 家商店，他购买了一件价值 $A_i$ 日元的商品，并支付了 $B_i$ 日元。其中满足 $A_i \leq B_i$。若 $S_i =$ keep，则他未领取找零；若 $S_i =$ take，则他领取了找零。
求他相较于“在每家商店都领取找零”的情形所损失的金额。具体而言：

• 设 $X$ 日元为高桥最终剩余的钱数；
• 设 $Y$ 日元为高桥在“每家商店都领取找零”的情形下最终剩余的钱数。

请计算 $Y - X$。

The input is given from Standard Input in the following format:

$N$
$A_1$ $B_1$ $S_1$
$A_2$ $B_2$ $S_2$
$\vdots$
$A_N$ $B_N$ $S_N$

输入从标准输入给出，格式如下：

$N$
$A_1$ $B_1$ $S_1$
$A_2$ $B_2$ $S_2$
$\vdots$
$A_N$ $B_N$ $S_N$

Output the amount of money Takahashi lost compared to the case where he received the change at every store.

输出高桥君相较于在每家商店都找零的情况下所损失的金额。

Sample 1 Explanation:
Takahashi's actions are as follows.

• At the first store, he bought an item worth $1$ yen, paid $2$ yen, and did not receive the change.
• At the second store, he bought an item worth $3$ yen, paid $6$ yen, and received the change.
• At the third store, he bought an item worth $5$ yen, paid $9$ yen, and did not receive the change.

Constraints

• $1 \leq N \leq 100$
• $1 \leq A_i \leq B_i \leq 100$
• $S_i$ is keep or take.
• $N, A_i, B_i$ are all integers.

样例 1 解释：
高桥的行为如下：

• 在第一家商店，他购买了一件价值 $1$ 日元的商品，支付了 $2$ 日元，且未领取找零。
• 在第二家商店，他购买了一件价值 $3$ 日元的商品，支付了 $6$ 日元，且领取了找零。
• 在第三家商店，他购买了一件价值 $5$ 日元的商品，支付了 $9$ 日元，且未领取找零。

限制条件

• $1 \leq N \leq 100$
• $1 \leq A_i \leq B_i \leq 100$
• $S_i$ 为 keep 或 take。
• $N, A_i, B_i$ 均为整数。
