Thanks again dude. Will get back to you after trying out your method.

Ok, I will attach the whole file along with this post.

I agree with chris. Considering your first question, another way to get the digits in reverse order is storing remainder, keep dividing the original no by 10 until the number comes to a single digit....

If i had the solution, i wouldn't be posting here would i? ;) I tried to solve that problem and came up with a code. The code doesnt have any syntax errors, compiles with a single warning. But im not...

PROBLEM :

A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.

Find the largest palindrome made from the...

Thanks Adam. I will check for the out of bounds possibility while using count.

Sorry, i forgot to replace all the FOR loops with the WHILE loop you gave me. When i replaced all of them, the code was working. But it deletes elements other than multiples of 2 from the vector....

StuXYZ & Rashakil, I was about to do wat stuXYZ has suggested. But i thought that i would check if im able to find prime nos as given in the wikipedia link (a simpler version). And i ended up in...

I've pasted the code which i came up with when i was trying to implement SoE and there seems to be some problems with the vector. Can you look into it plz?

Hey Adam, I tried this code(with the alteration of it++) in place of the for loop. But i keep getting the same error. Do i have to replace any other part of the code?

To be honest, my math is below par. Im working on improving it. Can you suggest me a better approach to this problem plz?

Thanks Adam. I will try out wat you have suggested.

QUESTION: The prime factors of 13195 are 5, 7, 13 and 29.

What is the largest prime factor of the number 600851475143 ?

I was trying to solve this problem. I was previously suggested to use the...

Thanks for explaining the logic dude. Am not that bright in math, im currently working on improving that part :) As per the code part, i thought continue statement will stop the current iteration,...

Ya. The first if loop checks for modulo of i, then the next if loop checks if i=19. If the first if loop is false, then in the else part i have chosen the next multiple of 20 to test. But, If both...

QUESTION : 2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest number that is evenly divisible by all of the numbers...

Thanks pal. I knew that there was a point to limit my prime factor search, but forgot the exact condition. I accept the fact that my math is below avg. Gotta improve a lot on that. I dont mind harsh...

Ques:

The prime factors of 13195 are 5, 7, 13 and 29.
What is the largest prime factor of the number 600851475143 ?

I came up with the following code. This did compile in VC++ Express Edition...

Thanks ancient dragon.

Thanks ancient dragon, your suggestion worked. But i still have some doubts.

1) Iterator is a pointer or subscript

2) When i increment the int vector's iterator, it increases by 1 or the size...

it is an integer pointer or something similar to an array subscript?

Oops. Forgot that part. Will an if loop checking if(it++ != tx.end()) help me solve this problem?

Hey ppl,

Hey salem, checked by removing the main() which i coded. The code is working fine after that. Thanks for the suggestion.

In this case, if i comment out the main() which i created, the method will be executed automatically by the other main()?

Hey ppl,
Im trying to solve some problems for topcoder website for practice purposes. But the compiler shows the following error for the codes i've been compiling. I have no problems...

Thanks sanzilla.

@Waltp

I don't need an array for this, but i need it for the next step. Plz see my first post. It has the complete statement.

@Sanzilla

Thanks man. Im not aware of Vector concept in STL. Any links that can help me?

@gregorynoob

Will the concept work well if the number that repeats isn't in the starting position of...

@sanzilla

You are right. I don't need just answers. I figured out till extracting digits. I want info on how to proceed further. I can create a very large array to store the set T(X) which results...

Sorry, forgot to mention the algorithm i had in mind. I can proceed till generating the T(X) set by seperating the digits. Iam unsure about how to proceed further without wasting memory/creating...

Hey ppl,
I was browsing thro the topcoder sample problems and came up with this one. Plz suggest some good algorithm for this.

Thanks VernonDozier. That explains things. And do you have any clue about why im getting the error which i've edited in my previous post?

Thanks a lot prabhakar. I forgot to mention what the code is for. Forgive me as this is my first post. This program is for calculating the number of letters from words with only alphabets and the...

Thanks for the suggestion man. Will try it now.

My code had some logical errors in it. I got some output, but its not the expected output for the problem. This was when i used Borland C++. When i pasted the same code in the topcoder's compiler, im...

I didn't get any errors in Borland C++ compiler. I was just getting wrong outputs. But when i used this code on the compiler given in topcoder application, it gives me linking error. And i've tried...

Guys,
Im not very experienced in C++. I was practicing problems from topcoder to improve my knowledge in C++. I've posted the code i used for solving a problem statement given by topcoder...
