A string parameter and returns new string with all the letters of the alphabet that are not in the argument string. The letters in the returned string should be in alphabetical order. The implementation should uses a histogram from the histogram function
Explanation:
The below code is written in python :
alphabet = "abcdefghijklmnopqrstuvwxyz"
test_dups = ["zzz","dog","bookkeeper","subdermatoglyphic","subdermatoglyphics"]
test_miss = ["zzz","subdermatoglyphic","the quick brown fox jumps over the lazy dog"]
def histogram(s):
d = dict()
for c in s:
if c not in d:
d[c] = 1
else:
d[c] += 1
return d
def has_duplicates(s):
for v in histogram(s).values():
if v > 1:
return True
return False
def test_dups_loop():
for s in test_dups:
print(s + ':', has_duplicates(s))
def missing_letters(s):
r = list('abcdefghijklmnopqrstuvwxyz')
s = s.lower()
for c in s.lower():
if c in r:
r.remove(c) # the first matching instance
return ''.join(r)
def test_miss_loop():
for s in test_miss:
print(s + ':', missing_letters(s))
def main():
test_dups_loop()
test_miss_loop()
if __name__ == '__main__':
main()
Answer:
1. multiplying two numbers when you meant to add them - Logical Error
2. dividing by zero - Compile time error
3. semi colon at the end of a programming statement - Logical error
4. wrong in output - Run time error
5. when you should have typed a - Compile time error
6. producing inaccurate results - Logical error or Run time error
Explanation:
Compile time error is a lack in computer programming which causes to violate the rules which are defined by user in the program.
Run time error produces wrong outputs. It causes lags in the softwares which makes the output inefficient. It even causes programs crash when the output is just seconds away.
Logical error is the situation where programs completes the task assigned but with the wrong syntax. The output is produced with some abnormality.
