Provide tags and a correct Python 3 solution for this coding contest problem.
As it's the first of April, Heidi is suspecting that the news she reads today are fake, and she does not want to look silly in front of all the contestants. She knows that a newspiece is fake if it contains heidi as a subsequence. Help Heidi... | instruction | 0 | 35,661 | 0 | 71,322 |
Tags: implementation, strings
Correct Solution:
```
s = input()
i = -1
for ch in 'heidi':
i = s.find(ch, i+1)
if i < 0:
print('NO')
break
else:
print('YES')
