A program to find the length of the string "refrigerator" without using len function.

• a = "refrigerator"

  count = 1

  for i in a:

  count = count+1

  count = count+1

  print count

• a = "refrigerator"

  count = 1

  for i in a:

  count = count+a[i]

What is the output for the following code:

def char_frequency(str1):

dict = {}

for n in str1:

keys = dict.keys()

if n in keys:

dict[n] += 1

else:

dict[n] = 1

return dict

print(char_frequency('google.com'))

• {'o': 0, '.': 1, 'g': 2, 'l': 1, 'e': 1, 'c': 2, 'm': 0}

• {'o': 5, '.': 1, 'g': 2, 'l': 1, 'e': 1, 'c': 2, 'm': 1}

• {'o': 3, '.': 1, 'g': 2, 'l': 1, 'e': 1, 'c': 0, 'm': 0}

• {'o': 3, '.': 1, 'g': 2, 'l': 1, 'e': 1, 'c': 1, 'm': 1}

Given your function, what is the correct output:

def chars_mix_up(a, b):

new_a = b[:2] + a[2:]

new_b = a[:2] + b[2:]

return new_a + ' ' + new_b

print(chars_mix_up('abc', 'xyz'))

• Sample String : 'abc', 'xyz'

  Expected Result : 'xyc abz'

• Sample String : 'abc', 'xyz'

  Expected Result : 'xbc ayz'

• Sample String : 'abc', 'xyz'

  Expected Result : 'xyc abc'

• Sample String : 'abc', 'xyz'

  Expected Result : 'ayc xbz'
