Hey everyone 
I’m trying to understand the difference between KMP and the Z Algorithm for pattern searching, but I’m a bit confused about when to use which one.
From what I know, both are efficient string matching algorithms with linear time complexity, but they use different approaches — KMP builds an LPS array, while the Z Algorithm builds a Z array.
Can someone explain in simple terms how they actually differ in logic and practical use? Also, in interviews or competitive programming, is one preferred over the other?
Would really appreciate a short and clear explanation. Thanks in advance
