1. Identify and underline the errors in the code given below. Also, write the correct code.

(a) # Program to display all numbers between 1 and 10 in decreasing order.
for num in range(1, 10, -1):
print(num)
(b) # Program to print the sum of numbers from 1 to 20.
sum = 1
num = 1
while num < 20:
sum = sum + num
print(“The sum of numbers from 1 to 20 = ” sum)
