TCS CodeVita previous years questions – 2014 Problem : Matrix Rotations You are given a square matrix of dimension N . Let this matrix be called A . Your task is to rotate A in clockwise direction by S degrees, where S is angle of rotation. On the matrix, there will be 3 types of operations viz. Rotation Rotate the matrix A by angle S, presented as input in form of A S Q uerying Query the element at row K and column L, presented as input in form of Q K L U pdation Update the element at row X and column Y with value Z, presented as input in form of U X Y Z Print the output of individual operations as depicted in Output Specification Input Format: Input will consist of three parts, viz. 1. Size of the matrix (N) 2. The matrix itself (A = N * N) 3. Various operations on the matrix, one operation on each line. (Beginning either with A, Q or U) -1 will represent end of input. Note: Angle of rotation will a...
