I'm new to Python 3, and I tried to test if my palindrome code works and passes most of the edge cases, so I created the following 2 Python files. And I was wondering if that is sufficient for my palindrome function. I think I have exhausted all of the cases.

A function that strips all non-letters, lowercases the result and then only compares the initial with the final character would survive the tests, but shouldn't.

Returning true if only any character matches instead of all is a common mistake, therefore the tests should prevent this mistake from being made. Sign up to join this community.

And lots of people you call ma'am — for instance, your female superior officer in the military — are definitely not running brothels.

No, all of those are gigs. When my dad lived in Georgia, my friends and I used to go out in the swamp at night with a bright light and go frog giggin'. A frog gig is a pole about a man's height long with four or five tines on the end, like a multi-pronged Neptune's trident. You shine a bright light into the swamp and when you see the eyes reflected which blinds the frog temporarily you spear "gig" the frog on the end and flip it into the boat Works for flatfish like flounder too if you use a bigger gig.

How is the frog or fish clue better? Hardly anyone myself included would get that and it could easily be hook, rod, etc. My brothers used to go frog gigging. Maybe it's a southern US thing. Fried frog legs were as close as we got to gourmet food back then. Just remember to clip the nerve in the legs or they would hop out of the frying pan while cooking.

I agree, the frog clue would probably add to the difficulty, but none of the other possible answers suggested are palindromes. I'm confused by the clue to "eve". Is that word specifically used for past evenings? Otherwise, great quiz! It is often used as the eve before something else. That is correct, even though it never made sense to me. It seems as though Christmas Eve should be the evening of Christmas day, not the night before. That has now led to the paradoxes of "Christmas Eve morning or Christmas Day night".A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward.

When the search for a match requires something more than a direct match, the pattern includes special characters. We check the end from each part and divide the number of iterations inside the FOR loop by two. I hope you found this helpful.

Regular expressions are patterns used to match character combinations in strings. Check for Palindromes With Built-In Functions For this solution, we will use several methods: The toLowerCase method to return the calling string value converted to lowercase.

The replace method to return a new string with some or all matches of a pattern replaced by a replacement. We will use one of the RegExp we just created earlier. The split method splits a String object into an array of strings by separating the string into sub strings. The reverse method reverses an array in place.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

This is some code that determines if a string of characters is a palindrome or not. My professor says that there is a performance issue with the program, but I can't quite put my finger on it. Can someone find out the 'performance' issue?

Initially, I thought maybe the process is slower as it uses two memory containers, as opposed to simply comparing two halves of a single string. While it is not quite definitive, it looks like you use using namespace std.

That namespace is not designed for wholesale inclusion, being vast and subject to change at the whim of the implementation, aside from providing what is standardised. You should desist from using std::endlas spurious manual flushing flushes any pretense at performance down the drain.

For those rare cases where it is actually necessary for correctness, use std::flush for explicitness. You assume reading from std::cin always succeeds. That's generally unsupportable, please handle failure gracefully. You are reading character-by-character. Each and every read has significant overhead, which you could simply avoid by using std::getline.

Using the proper abstraction is also significantly more readable. You are storing the input twice, once in a std::queue and once in a std::stack. Even only storing it in just one std::deque the underlying implementation for both would be a considerable improvement.

Consider encapsulating the test whether the input is a palindrome into its own reusable function, separate from actually getting it. Testing whether something is a palindrome seems a favorite passtime of many beginners. The important points are avoiding expensive copies, and only comparing each element once. If you want one of two values, conditional on some expression, consider the conditional operator expr?

It is designed for that. I think you hit on an excellent idea right there. I'd read a line of input into a string, the compare the first half of the string to the second half in reverse order.

If you wanted to minimize changes to your code, you could just read the string into the deque, then to do the comparison, pop one element from the front, and one element from the back, and compare them. The input was palindromic if and only if all the elements match until the deque has fewer than two elements.

Possible Duplicate: to find if a given string is palindrome or is not palindrome.

Reverse a string or linked list using stack.

I need to create a program that allows a user to input a string and my program will check to see if that string they entered is a palindrome word that can be read the same backwards as it can forwards. This constructor of string takes a beginning and ending iterator and creates the string from the characters between those two iterators. Since rbegin is the end of the string and incrementing it goes backwards through the string, the string we create will have the characters of input added to it in reverse, reversing the string.

This does not take into account capitalisation or spaces, so you'll have to improve on it yourself. Learn more. Check if a string is palindrome [duplicate] Ask Question. Asked 8 years, 4 months ago.
