Carefully go through the code given below and answer the questions based on it :
in1Str = input(" Enter string of digits: ")
in2Str = input(" Enter string of digits: ")
if len(in1Str)>len(in2Str):
small = in2Str
large = in1Str
else:
small = in1Str
large = in2Str
newStr = ''
for element in small:
result = int(element) + int(large[0])
newStr = newStr + str(result)
large = large[1:]
print (len(newStr)) # Line 1
print (newStr) # Line 2
print (large) # Line 3
print (small) # Line 4

Answer
Option 1 — 369
Explanation
For loop executes 3 times as length of smaller input is 3.
1st Iteration
result = 2 + 1
⇒ result = 3
newStr = '' + '3'
⇒ newStr = '3'
large = 2345
2nd Iteration
result = 4 + 2
⇒ result = 6
newStr = '3' + '6'
⇒ newStr = '36'
large = 345
3rd Iteration
result = 6 + 3
⇒ result = 9
newStr = '36' + '9'
⇒ newStr = '369'
large = 45
Final value of newStr is '369'.

Carefully go through the code given below and answer the questions based on it :
inputStr = input(" Give me a string:") biglnt = 0 littlelnt = 0 otherlnt = 0 for ele in inputStr: if ele >= 'a' and ele <= 'm': # Line 1 littlelnt = littlelnt + 1 elif ele > 'm' and ele <= 'z': biglnt = biglnt + 1 else: otherlnt = otherlnt + 1 print (biglnt) # Line 2 print (littlelnt) # Line 3 print (otherlnt) # Line 4 print (inputStr.isdigit()) # Line 5
Give the input Hi Mom, what changes result from modifying Line 1 from
if ele >= 'a' and ele <='m' to the expression
if ele >= 'a' and ele < 'm'?- No change
- otherlnt would be larger
- littlelnt would be larger
- biglnt would be larger
- None of these
