Rewrite following code fragments using while loops

min = 0 
max = num 
if num < 0 :
    min = num 
    max = 0 
# compute sum of integers from min to max 
for i in range(min, max + 1): 
    sum += i

Rewrite following code fragment using while loops :

for i in range(1, 16) :
  if i % 3 == 0 :      
     print (i)

Write a short program to print the following series :

1 -4 7 -10 ………. -40

Predict the output of the following code fragments:

count = 0         
while count < 10:
    print ("Hello")
    count += 1
