题目描述
Anton decided to get ready for an Olympiad in Informatics. Ilya prepared $n$ tasks for him to solve. It is possible to submit the solution for the $i$ -th task in the first $d_{i}$ days only. Anton cannot solve more than one task a day. Ilya estimated the usefulness of the $i$ -th tasks as $r_{i}$ and divided the tasks into three topics, the topic of the $i$ -th task is $type_{i}$ .
Anton wants to solve exactly $a$ tasks on the first topic, $b$ tasks on the second topic and $c$ tasks on the third topic. Tell Anton if it is possible to do so, and if it is, calculate the maximum total usefulness of the tasks he may solve.

输入格式
The first line of input contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases.
The first line of each test case contains four integers $n, a, b, c$ ( $1 \le n \le 10^5$ , $0 \le a, b, c \le n$ ).
The following $n$ lines contain three integers each — $r_i, type_i, d_i$ ( $0 \le r_i \le 10^{9}$ , $1 \le type_i \le 3$ , $1 \le d_i \le n$ ).
The sum of $n$ over all test cases does not exceed $10^5$ .

输出格式
For each test case print $-1$ if Anton cannot reach his goal; otherwise, print the maximum usefulness of the tasks he will solve.
