Question

Write the following user-defined functions in Python to perform the specified operations on ClrStack:

(i) push_Clr(ClrStack, new_Clr): This function takes the stack ClrStack and a new record new_Clr as arguments and pushes this new record onto the stack.

(ii) pop_Clr(ClrStack): This function pops the topmost record from the stack and returns it. If the stack is already empty, the function should display the message "Underflow".

(iii) isEmpty(ClrStack): This function checks whether the stack is empty. If the stack is empty, the function should return True, otherwise the function should return False.

Accepted Answer

def push_Clr(ClrStack, new_Clr):
    ClrStack.append(new_Clr)

def pop_Clr(ClrStack):
    if len(ClrStack) == 0:
        print("Underflow")
    else:
        return(ClrStack.pop())

def isEmpty(ClrStack):
    if len(ClrStack) == 0:
        return True
    else:
        return False
