5. Find the output of the following program segments:
i. a = 110
while a > 100:
print(a)
a -= 2
ii. for i in range(20,30,2):
print(i)
iii. country = 'INDIA'
for i in country:
print (i)
iv i = 0; sum = 0
while i < 9:
if i % 4 == 0:
sum = sum + i
i = i + 2
print(sum)
v. for x in range(1,4):
for y in range(2,5):
if x * y > 10:
break
print (x * y)
vi. var = 7
while var > 0:
print ('Current variable value: ', var)
var = var -1
if var == 3:
break
else:
if var == 6:
var = var -1
continue
print ("Good bye!")
