Since java.util.PriorityQueue doesn't use the Cloneable interface, I think it's safe to say that Serializable interfaces are implemented in all instances.
Answer:
weights = []
total = 0
max = 0
for i in range(5):
weight = float(input("Enter weight " + str(i+1) + ": "))
weights.append(weight)
total += weights[i]
if weights[i] > max:
max = weights[i]
average = total / 5
print("Your entered: " + str(weights))
print("Total weight: " + str(total))
print("Average weight: " + str(average))
print("Max weight: " + str(max))
Explanation:
Initialize the variables
Create a for loop that iterates 5 times
Get the values from the user
Put them inside the array
Calculate the total by adding each value to the total
Calculate the max value by comparing each value
When the loop is done, find the average - divide the total by 5
Print the results
SET is used to change the value of an entire column in a db.
