please make sure, the contents in the slides are neither at the very top nor at the very bottom. it becomes difficult to pause and read.

5:19 shouldn't in the third line, while condition be '(num>9)'? Because if input is '10' then its number of digits if '2' but this code will show '1'.

[bhanugupta]

n = int(input())
fac = 1
if (n < 0):
print("not defined")
else:
for i in range(1, n+1):
fac = fac * i
print(fac)

08:40: Left code will give you 1 for 10.
So On the left code, condition of while loop should be num>9

[bhanugupta]

# find the sum of all digits in the given number

n = int(input())
sum = 0
while(n>0):
l = n % 10
sum += l
n = n // 10
print(sum)

19:12 9th problem statement, there is all positive numbers so I don't understand how range is determined?
