有一个N*N的字符矩阵，从上到下依次记为第1行，第2行，……，第N行，从左至右依次记为第1列，第2列，……，第N列。

对于这个矩阵会进行一系列操作，但这些操作只有两类：

(1) R: 将矩阵逆时针旋转90度；

(2) P x y: 将此时第x行第y列的字符打印出来，其中1 <= x, y <= N。



输入数据的第一行包含一个整数T (1 <= T <= 20)，表示接下来一共有T组测试数据。

对于每组测试数据，第一行包含一个整数N (1 <= N <= 300)，含义同上。接下来一共有N行，每行均包含N个大写字母，描述了这个矩阵的初始情况。再接下来一行包含一个整数M (1 <= M <= 10000)，表示一共对矩阵进行了M次操作。接下来M行，每行均包含一个符合上述格式的操作，依次描述了这M个操作。



对于每个第(2)类操作，用一行打印出指定位置的字符。

相邻的两组测试数据中间用一个空行隔开。-There is an N* N matrix characters,　top to bottom in mind for the first row, second row, ......, the first N rows,　left to right followed credited as the first one, the first two, ...... first N columns. For this matrix will conduct a series of operations, but these operations are only two types: (1) R: 90 degrees counter-clockwise rotation matrix　(2) P xy: the character in the first column x row y print it out, which 1 < = x, y < = N. The first line of input data contains an integer T (1 < = T < = 20), a total of T represents the next set of test data. For each test, the first line contains an integer N (1 < = N < = 300), as defined above. Next, a total of N lines, each line containing N uppercase letters, describing the initial situation this matrix. The next line contains an integer M (1 < = M < = 10000), shows a total of M times for the matrix operation. Next M rows, each row contains an operation in line with the above format, in turn describes the M operation.
