The Free Meteor Association (FMA) has got a problem: as meteors are moving, the Universal Cosmic Descriptive Humorous Program (UCDHP) needs to add a special module that would analyze this movement.

UCDHP stores some secret information about meteors as an n × m table with integers in its cells. The order of meteors in the Universe is changing. That's why the main UCDHP module receives the following queries:

• The query to swap two table rows;
• The query to swap two table columns;
• The query to obtain a secret number in a particular table cell.

As the main UCDHP module is critical, writing the functional of working with the table has been commissioned to you.

The first line contains three space-separated integers n, m and k (1 ≤ n, m ≤ 1000, 1 ≤ k ≤ 500000) — the number of table columns and rows and the number of queries, correspondingly.

Next n lines contain m space-separated numbers each — the initial state of the table. Each number p in the table is an integer and satisfies the inequality 0 ≤ p ≤ 10⁶.

Next k lines contain queries in the format "s_i x_i y_i", where s_i is one of the characters "с", "r" or "g", and x_i, y_i are two integers.

• If s_i = "c", then the current query is the query to swap columns with indexes x_i and y_i (1 ≤ x, y ≤ m, x ≠ y);
• If s_i = "r", then the current query is the query to swap rows with indexes x_i and y_i (1 ≤ x, y ≤ n, x ≠ y);
• If s_i = "g", then the current query is the query to obtain the number that located in the x_i-th row and in the y_i-th column (1 ≤ x ≤ n, 1 ≤ y ≤ m).

The table rows are considered to be indexed from top to bottom from 1 to n, and the table columns — from left to right from 1 to m.

For each query to obtain a number (s_i = "g") print the required number. Print the answers to the queries in the order of the queries in the input.
