Can you help me to answer the following questions?

A solution to the MCGW problem can be expressed in different forms, but it is not as simple for human to verify whether a given solution is correct. Here we are to develop a Python program to help verifying the correctness of a given solution. To solve the problem systematically, we are to develop a few functions and break up the original bigger problem into several smaller problems. The following order of breaking down the problem is not the only way, but is a reasonable way. You can assume that the input string is correct in that it does not contain any special character, nor there is a missing of key symbols like \"I\" and \">\". - Develop a Python function islega1(state) to help in (b). It takes as input a state and returns True if the state is legal (i.e. goat not eating cabbage and not eaten by wolf) and False otherwise. Provide appropriate comments in your function. Here are some sample outputs from your function: >>> print(islegal("GlMCW")) True >>> print(islegal("MWlCG")) False
