However, it is possible to perform some string pattern matching within the same framework that has been discussed throughout this article.

Famous quotes containing the words pattern and/or strings:
“His talent was as natural as the pattern that was made by the dust on a butterflys wings. At one time he understood it no more than the butterfly did and he did not know when it was brushed or marred. Later he became conscious of his damaged wings and of their construction and he learned to think and could not fly any more because the love of flight was gone and he could only remember when it had been effortless.”
—Ernest Hemingway (18991961)
“When my lover came to bed,
the knot came untied
all by itself.
My dress,
held up by the strings of a loosened belt,
barely stayed on my hips.
Friend,
thats as much as I know now.
When he touched my body,
I couldnt at all remember
who he was,
who I was,
or how It was.”
—Amaru (c. seventh century A.D.)
