P1032 String Conversion and p1032 String ConversionDescription It is known that there are two strings A, B and A set of string conversion rules (up to 6 Rules ): A1-> B1 A2-> B2 The meaning of the rule is: the sub-string A1 in A $ can be changed to B1, A2 can be changed to B2 .... For example, A = 'abc' B = 'xyz' The conversion rules are as follows: 'Abc'-> 'xu '

In the 3D world, we need to constantly convert coordinates in various spaces. For example, we need to convert an object from a model space to a world space, and convert points in a world space to a view space of a camera. We know that coordinate conversion can be achieved by multiplying a vector and a conversion matrix. Note that if the row vector is selected, the matrix is placed on the right side of the m
