{"ops":[{"insert":"Matrix Rotations\nYou are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.\n\nRotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.\n\nUpdate: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.\nAfter the update, all the previous rotation operations have to be applied to the updated initial matrix.\n\nQuerying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.\n\n Input\n\nThe first line contains a single integer N.\nNext N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).\nNext lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).\n-1 will represent the end of input.\n\nOutput\n\nFor each Query operation print the element present at row index K and colum index L of the matrix in its current state.\n\nExplanation\n\nFor Input:\n2\n1 2\n3 4\nR 90\nQ 0 0\nQ 0 1\nR 90\nQ 0 0\nU 0 0 6\nQ 1 1\n-1\n\nInitial Matrix\n1 2\n3 4\n\nFor R 90, clockwise rotation by 90 degrees, the matrix will become\n3 1\n4 2\n\nFor Q 0 0, print the element at row index 0 and column index 0 of A, which is 3. \nFor Q 0 1, print the element at row index 0 and column index 1 of A, which is 1. \n\nAgain for R 90, clockwise rotation by 90 degrees, the matrix will become\n4 3\n2 1\n\nFor Q 0 0, print the element at row index 0 and column index 0 of A, which is 4. \n\nFor U 0 0 6, update the value at row index 0 and column index 1 in the initial matrix to 6. So the updated matrix will be,\n6 2\n3 4\nAfter updating, we need to rotate the matrix by sum of all rotation angles applied till now(i.e. R 90 and R 90 => 90 + 90 => 180 degrees in clockwise direction).\nAfter rotation the matrix will now become\n4 3\n2 6\n\nNext for Q 1 1, print the element at row index 1 and column index 1 of A, which is 6. \n\noutput \n3\n1\n4\n6\n\nSample Input 1\n2\n1 2\n3 4\nR 90\nQ 0 0\nQ 0 1\nR 90\nQ 0 0\nU 0 0 6\nQ 1 1\n-1\n\nSample Output 1\n3\n1\n4\n6\n\nSample Input 2\n2\n5 6\n7 8\nR 90\nQ 0 1\nR 270\nQ 1 1\nR 180\nU 0 0 4\nQ 0 0\n-1\n\nSample Output 2\n5\n8\n8\n\ni want exact sample outputs sir\n"}]}
