Rather than doing-
m= (n* 100), do this:
m = (int) (n * 100 + 0.5) to avoid floating point error.

you should get memory limit exceed.How much memory you used- int mark[10000][10000]; int store[10000][10000]; Its a simple 1-dimentional DP problem.look at the sample input 4 1 2 4 6 Declare an array A[50000] because highest value may be 100*500=50000 and and fill it by 0. now add all element .Sum=1...

Your program even don't pass the sample input.

Your ans is right.
Correct output-

Code: Select all

The nicest part of route 1 is between stops 1 and 4
The nicest part of route 2 is between stops 4 and 7

First Ans-
There exist a thread for problem no. 392.So why you are creating a new thread.

And then try this-

Code: Select all

-1 -1 2 3 4 5 0 0 0

your output:-

Code: Select all

-x^8 - x^7 + x^6 + x^5 + x^4 + x^3

Actual output:-

Code: Select all

-x^8 - x^7 + 2x^6 + 3x^5 + 4x^4 + 5x^3

Try this-

Code: Select all

your code output-
The nicest part of route 1 is between stops 5 and 7

Answer-
The nicest part of route 1 is between stops 1 and 4

@shafaet_du, Some of your input is wrong.Because the problem statement clearly says-

There is always a space (ASCII #32) immediately after each operand.

Ok,tell me what will be the output of

Code: Select all

your code produce 1.And the correct answer is 2.

You have problem in reading input.When you have to consider empty string you need to use gets().So use gets.and when you use gets() keep one thing in mind you have to read a dummy string if you take input before for taking newline.Like : scanf("%d",&n); gets(text); //dummy input for(j=1;j<=n;j++) { ...

what is the number of composite prime less than 2^20(1048556).Is it 227886??

sazzadcsedu

No, I don't think so.Here is an efficient way-

Code: Select all

I have no time to explain my code.So its upto you to understand the code.Dont submit it without understanding.And let me know after copying so that i can remove it.

This problem can be solved in many ways.I have solved it in the following way:- 1.Create a suffix array. 2.Sort the suffix array using qsort(). 3.Find the longest match(pattern) from suffix array. 4.Then using Knuth-Moris-Pratt find the no. of occurrence of pattern in the given string. It takes 0.11...

You are printing an extra space here:

Code: Select all

 
        s[j] = '\0';
        reverse(s, s+j);
        printf("%s(space)", s);

        Here you printing extra space,replace space with another character,you will find the problem.
