Answer:
The function is as follows:
def compare_prefix(strX,strY):
prefix=set()
for i in range(len(strX)):
for j in range(i+1,len(strX)):
chk =strX[i:j+1]
if chk in strY:
prefix.add(chk)
sort_prefix = sorted(prefix)
rev_sort_prefix = sorted(prefix,reverse=True)
return(sort_prefix,rev_sort_prefix)
Explanation:
This defines the function
def compare_prefix(strX,strY):
This creates an empty set, prefix
prefix=set()
This iterates through each character in strX
for i in range(len(strX)):
This iterates through every other character in strX
for j in range(i+1,len(strX)):
This gets the prefix of strX by concatenating strings from i to j + 1
chk =strX[i:j+1]
This checks if the prefix is in strY
if chk in strY:
If yes, the string is added to set prefix
prefix.add(chk)
This sorts prefix
sort_prefix = sorted(prefix)
This reverses the sorted prefix
rev_sort_prefix = sorted(prefix,reverse=True)
This returns the sorted and reversed prefix
return(sort_prefix,rev_sort_prefix)
