rlock 1.3 es nments osoft Teams es 6 We have four functions, func1, func2, func3, and complex_call, all of which take no parameters and only show text. The first three functions all print their function name and then might call zero or more of the other functions. The complex_call function does not print its name, but is the first function called and might call one or more of the other function. None of the functions are recursive. 1.a Using what you know about the call stack, implement all four functions so that your implementation displays the same text as above. 1.b In a comment labeled "1.b" in your complex_call function, explain what function or functions are called at the deepest stack level
