Create a Flowchart:

# User defined function for logic OR
# The function takes two parameters and returns a single int
def OR(a: int, b: int)->int:
    # If a is equal to 1 return 1
    if a == 1 :
        return 1
    # If b is equal to 1 return 1
    elif b == 1 :
        return 1
    # If a and b is equal to 0 return 0
    else :
        return 0


# User defined function for logic NOR
# The function takes two parameters and returns a single int
def NOR(a: int, b: int)->int:
    # If a is equal to 0 and b is also equal to 0 return 1
    if a == 0 and b == 0 :
        return 1
    # If a is equal to 0 and b is equal to 1 return 0
    elif a == 0 and b == 1 :
        return 0
    # If a is equal to 1 and b is also equal to 0 return 0
    elif a == 1 and b == 0 :
        return 0
    # If a is equal to 1 and b is also equal to 1 return 0
    elif a == 1 and b == 1 :
        return 0


# User defined function for logic AND
# The function takes two parameters and returns a single int
def AND(a: int, b: int)->int:
    # Return 1 if both a and b are equal to 1
    if a == 1 and b == 1 :
        return 1
    # Return 0 otherwise
    else :
        return 0


# User defined function for defining a logical circuit
# The function takes three parameters and returns a single int
def logic_circuit(A: int, B: int, C: int)->int:
# Calling above defined functions with
# parameters passed to them
# The function calls simulate a logic circuit
# The result is stored in a variable Q
# The value in Q is returned
    Q = OR(NOR(A, B), AND(B, C))
    return Q

# User inputs for bits A, B and C
while(True):    #infinte loop
    A = int(input("Enter binary input For A: "));   #ask for input
    if(A==0 or A==1):           #if input is 0 or 1
        break;                  #exit from while loop

while(True):    #infinte loop
    B = int(input("Enter binary input For B: "));   #ask For input
    if(B==0 or B==1):           #if input is 0 or 1
        break;                  #exit from while loop
    
while(True):    #infinte loop
    C = int(input("Enter binary input For C: "));   #ask for input
    if(C==0 or C==1):           #if input is 0 or 1
        break;                  #exit from while loop

# Calling function logic_circuit with A, B and C
# passed as parameters
# The result is stored in a variable Q
# The value of Q is returned

Q = logic_circuit(A, B, C)
print("Output: ", Q)
