What is wrong with this piece of code? I am trying to create a list given specific strings and an input, then find the largest word and return/print it. def largest(words):

Length = 0
Word = ""

largest_word = ""
num_Words = len(words)

for x in range(0, num_Words, 1):
largest_word = words[x]
largest_length = len(largest_word)
if (largest_length >= Length):
largest_length = Length
largest_word = Word

return largest_word

user_pet = input("Enter a pet: ")
y = ["cat", "dog", "hamster", user_pet]
largest_petname = largest(y)
print(largest_petname)

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
