Determine whether two characters are ectopic characters:
For example, abcda is the ectopic character of aabcd
'''
 #Method 1:
print(sorted( ' abcda ' )==sorted( ' aabcd ' ))
 '''
 efficiency O(
 NlogN) '
 '' #Method 2: The idea of ​​hashing. Use ord to become asci code
a='abcda'
b='aabcd'
d=[0]*256
for i in range(len(a)):
    d[ord(a[i])] += 1 
    d[ord(b[i])] -= 1 
print(d ==[ 0 ]* 256 )
