Hello, friends. I did the fourth challenge on Project Euler and I'd like to know what I can do to improve the efficiency of my code. Right now it takes 1.562s to run and the source code is as follows: #include <iostream> #include <string.h> using namespace std; int Number = …

Hello programmers! After covering the basics of STL, I decided to complete the following assignment: `Write a function template palindrome that takes a vector parameter and returns true or false according to whether the vector does or does not read the same forward a backward.` So, for example, a vector …

I get an error when I try to compile my code. I can't figure it out. It says it's not declared but I think it is declared. // // // This menu-driven program is used to allow the user to choose // an application to be executed. // // // …

A palindrome is a word or sentence that reads the same forward as it does backward. Write C++ code that read string consist of 6 characters only and check if the string palindrome word or NOT.

SO guys I am supposed to be making a program that will check for a palindrome but, I can not get my code to work. It seems to be stuck on the cmp part. I am not sure if this is even right I dont have much experience with masm. …

http://ideone.com/H7YIwR Here's my code to find palindrome in string..But surely it's too slow..Is there any good algorithms for such problems..And for some cases it's not giving the right answer.Thanks for the help.

I a new c++ programmer, and i started to solve the SPOJ online challenges just practising , and because of my few experiance.. it gives me wrong answers alwayes.

I need to create a palindrome tester program that ignores spaces, punctuation and uppercase/lowercase to determine if the string given to the user is a palindrome (same beginning to end as end to beginning). HERE'S WHAT I HAVE SO FAR: String str, another = "y"; int left, right; Scanner scan …

Here is slow brute force way to find the largest palindromic product of three digit integers. You could do loop and break out of it if you go under the smaller number (the second one) of best solution found so far to be more efficient etc.

this program is to find the largest palindrome of 3 digit numbers.this code is workig for two digit numbers but it is not working for 3 digit numbers. `` #include<stdio.h> #include<conio.h> #include<math.h> void main() { int i,j,con=0; long int num=0,res=0; clrscr(); for(i=999;i>900;i--) { for(j=999;j>i;j--) { num=(i*j); con=pal(num); if(con==0&&num>=res) res=num; } …

Hey so this is my code for checking for palindromes...it compiles fine, the problem is it doesnt work. Basically I converted the four sentences into strings without spaces or other characters and added them to a new string called newstr....i used the newstr to check for a palindrome in the …

I'm trying to make a Palindrome program, that basically returns whatever you enter, just backwards. For some reason, the cNewArray is not only couting the original array backwards, but also the original array. For example if I enter "Hello" it returns "Hello = olleHHello". I'm very new to referencing pointers …

Hello! I need to write a program to find whether a word is a palindrome or not. What differentiates this from the other palindrome threads in this forum is that I can only use certain functions. They are: If statements, string functions (to upper, to lower, indoxof, length, substrings), for …
