A company conducted a coding test to hire candidates. $N$ candidates appeared for the test, and each of them faced $M$ problems. Each problem was either unsolved by a candidate (denoted by 'U'), solved partially (denoted by 'P'), or solved completely (denoted by 'F'). 

To pass the test, each candidate needs to either solve $X$ or more problems completely, or solve $(X-1)$ problems completely, and $Y$ or more problems partially.

Given the above specifications as input, print a line containing $N$ integers. The $i^{th}$ integer should be $1$ if the $i^{th}$ candidate has passed the test, else it should be $0$.

------ Input: ------

The first line of the input contains an integer $T$, denoting the number of test cases.
The first line of each test case contains two space-separated integers, $N$ and $M$, denoting the number of candidates who appeared for the test, and the number of problems in the test, respectively.
The second line of each test case contains two space-separated integers, $X$ and $Y$, as described above, respectively.
The next $N$ lines contain $M$ characters each. The $j^{th}$ character of the $i^{th}$ line denotes the result of the $i^{th}$ candidate in the $j^{th}$ problem. 'F' denotes that the problem was solved completely, 'P' denotes partial solve, and 'U' denotes that the problem was not solved by the candidate.

------ Output: ------

For each test case, print a single line containing $N$ integers. The $i^{th}$  integer denotes the result of the $i^{th}$ candidate. $1$ denotes that the candidate passed the test, while $0$ denotes that he/she failed the test.

------ Constraints  ------
$1 ≤ T ≤ 100$
$1 ≤ N ≤ 100$
$2 ≤ M ≤ 100$
$1 ≤ X, Y ≤ M$
$1 ≤ (X-1)+Y ≤ M$

- Sample Test 1: There are $4$ candidates and $5$ problems. Each candidate needs to solve $3$ or more problems completely, or $2$ problems completely and $2$ or more problems partially. Only the first and the second candidates satisfy this.

- Sample Test 2: The candidates need to either solve at least one problem completely, or they need to solve three or more problems partially. Only candidates $1$ and $3$ satisfy this.

- Sample Test 3: The candidate needs to either solve two or more problems completely, or solve at least one problems completely and two problems partially. The candidate does not satisfy this.
