How are following two code fragments different from one another? Also, predict the output of the following code fragments :

(a)

n = int(input( "Enter an integer:" ))
if n > 0 :
    for a in range(1, n + n ) :
        print (a / (n/2))
    else :
        print ("Now quiting")

(b)

n = int(input("Enter an integer:"))
if n > 0 :
    for a in range(1, n + n) :
        print (a / (n/2))
else :
    print ("Now quiting")

Rewrite the following code fragment using for loop:

i = 100
while (i > 0) :
    print (i)
    i -= 3

Rewrite the following code fragment using for loop:

while num > 0 :
    count += 1
    sum += num
        num –= 2
        if count == 10 :
            print (sum/float(count))
            break

Rewrite following code fragment 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
