We are given a string S, we need to find count of all contiguous substrings starting and ending with same character. Method 1 Simple : In this approach we use brute force and find all the sub-strings and pass them through our function checkEquality to see if starting and ending characters are same.
This solution also requires O n extra space as we one by one create all substrings. Method 3 Best approach : Now if we carefully observe then we can realize that the answer just depends on frequencies of characters in the original string.

This is similar to the way the brain responds to an arrangement of letters or words. As your brain deciphered each word in the example above, it also predicted which words would logically come next to form a coherent sentence.
However, even if you read that garbled example with ease, you probably didn't read every word correctly.Guess These Words Which Start And End With The Same Letter
You thought you did because you understood the sentence, but in addition to predicting what came next, your brain also filled in any gaps based on the subsequent words. If you've ever been stumped by a word jumble, you know it's not always easy to unscramble a certain assortment of letters. But what if the first and last letters of the word are in place? If you're familiar with the text below, you may think you'd still be able to read any word scrambled in such a fashion.

According to this memewhich claims to be based on Cambridge University research, we're able to read that passage because our brains process all of the letters in a word at once. Davis uses the following three sentences to illustrate how simply leaving the first and last letters of a word in place doesn't necessarily mean a sentence will still be easily readable.

A dootcr has aimttded the magltheuansr of a tageene ceacnr pintaet who deid aetfr a hatospil durg blendur. Having a little trouble with those last two? Each of these sentences becomes progressively more challenging to read because, even though Davis followed the rule dictated in the meme, he jumbled the letters more. You can read the original sentences at the bottom of Davis' article. First of all, function words like "the" and "be" remain unchanged, which preserves sentence structure and helps your brain make predictions about what's next.
You might not have even noticed those correctly spelled words because readers tend to gloss over function words when reading. Also, transpositions of adjacent letters — such as "porbelm for problem" — are easier to read than more distant transpositions.You've probably seen the classic piece of "internet trivia" in the image above before - it's been circulating since at least On first glance, it seems legit.
Because you can actually read it, right? But, while the meme contains a grain of truth, the reality is always more complicated. The meme asserts, citing an unnamed Cambridge scientist, that if the first and last letters of a word are in the correct places, you can still read a piece of text. The rest can be a total mess and you can still read it without problem.
This is because the human mind does not read every letter by itself but the word as a whole. In fact, there never was a Cambridge researcher the earliest form of the meme actually circulated without that particular additionbut there is some science behind why we can read that particular jumbled text.
The phenomenon has been given the slightly tongue-in-cheek name " Typoglycaemia ," and it works because our brains don't just rely on what they see - they also rely on what we expect to see.Nel lazio 31 casi,trend allo 0,4
Inresearchers from the University of Glasgow, conducting unrelated research, found that when something is obscured from or unclear to the eye, human minds can predict what they think they're going to see and fill in the blanks. However, the meme is only part of the story.
Matt Davis, a researcher at the University of Cambridge's MRC Cognition and Brain Sciences Unit, wanted to get to the bottom of the "Cambridge" claimsince he believed he should have heard of the research before. He managed to track down the original demonstration of letter randomisation to a researcher named Graham Rawlinson, who wrote his PhD thesis on the topic at Nottingham University in He conducted 16 experiments and found that yes, people could recognise words if the middle letters were jumbled, but, as Davis points out, there are several caveats.
It also helps to keep double letters together.
Last letter-first letter
There is evidence to suggest that ascending and descending elements play a role, too - that what we're recognising is the shape of a word. This is why mixed-case text, such as alternating capsis so difficult to read - it radically changes the shape of a word, even when all the letters are in the right place. If you have a play around with this generatoryou can see for yourself how properly randomising the middle letters of words can make text extremely difficult to read.
