Improvement of KMP algorithmThe KMP algorithm has some improved versions to speed up lookups, and can generally speed up the matching process with some information in the S string.For example, if S = "Aaaaaaaafaaaaaaaaaaaab", T = "Aaaaaaab".During the lookup process, the "F" in the middle of s plays a blocking role.

And in the coding process we often find that the design: a box background solid color (assuming: #f00), but with 75% opacity. Obviously, we can't simply set this up because we dom.style.backgroundColor = "#f00" don't have a translucent effect. Changed, we know that there is an RGBA in CSS3, which means
