What is the shortcut for Save As? How do you use the Control key? Control key Ctrl. How do I turn on keyboard shortcuts? How do I see all keyboard shortcuts? Here we can perform an optimization, instead of comparing from the front, how about comparing from the end? But as you might've guessed this has a huge flaw of, what if the end characters match but starting character mismatch. So we need a concrete algorithm that will skip characters such that overall character comparison decreases.
One thing which we could do is instead of moving the entire pattern, we move a part of the pattern. We match each character between mismatched string and pattern, then we check if we have any common characters, if we do then we move only part of those characters. In this case, we did 12 comparison operations and this will work if compare string and pattern from either side. This is a modified version of the original algorithm, the original algorithm found only the first instance of the pattern, here we're finding all the occurrences of the pattern.
Logically we must go back and match first "C" of the string with "C" of pattern, but doing so will mean that we are going back which we logically shouldn't or else we will be stuck in an infinite loop going back and forth.
To ensure that we keep on going forward with the matching process, we ensure that whenever we come across situations when there's a negative skip, we set skip to 1.
I found this on StackOverflow you can read it here but in a nutshell:. Pratcial usecase includes implementation of grep in GNU for string matching, chrome probably uses it for string search. Rabin Karp: Use O 1 auxiliary space, this performs better under searching for long words in a document containing many long words see StackOverflow link for more.
I hope you liked my explanation. I usually write about how to solve interview questions and real-life applications of algorithms. The algorithm which we will implement might be similar to the one used in Chrome, but since its Google we're talking about, they might've made optimizations.
The source code for the find in page is actually open source! You can see how it's implemented here: source. I read on StackOverflow that somewhere around when chrome was picking of, they shared how they've implemented a version of Boyer Moore's pattern matching algorithm.
But I couldn't find it on youtube. That code does not work for a string which is consisting of only the same character. Hey Akhil! Amazing article! I had always wondered how is chrome able to find matching strings so fast. One question, is this type of pattern matching slower or faster than using Regular Expressions say in python? It depends on the complexity of the regex you're searching with.
Use the up and down arrows to see every instance of the word or phrase, highlighted in yellow. The iPhone also has two built-in features that allow you to search for words or phrases within the Messages app. You can use either the search bar in the Messages app or the iOS Spotlight search function to search across your text message conversations for specific words.

You can also select Find under the Edit menu of your browser or app. You simply hold down the control key and F at the same time, and a window pops up asking if there's a word or phrase you need to find.
I hope you find them useful! This happens to me when I'm searching the web — Google finds the page I need, but then there's so much text on the page that I can't find what I was searching for in the first place. For an absurd example, let's say I want to find the quote that goes something like "I think therefore..
It brings me right where I wanted. Now I know it was Descartes who said "I think; therefore I am. Maybe you're like me and you just click "Agree" till the cows come home when it comes to software license agreements.

Did you know that Ctrl-F has another super power? It magically transforms into Find and Replace when you're in an editable content area like your blogging platform, or a word processing app. Here's one of my favorite ways to use this. You can use Ctrl-F to get rid of pesky extra spaces that people still use at the end of a sentence , even though it should only be one space.
