Prefix Replacement
Solve a medium-level problem of prefix replacement in a sentence using tries.
Problem statement
We can append some other words to a prefix to frame new words. For example, the prefix re
can be followed by words start
and cap
to form words restart
or recap
.
Given a list consisting of multiple prefixes and a sentence, replace all the words in the sentence with the prefix forming it. If a word can be replaced by more than one prefix, replace it with the prefix that has the shortest length.
Return the modified sentence after the replacement.
