Given an array of integers and a range find the count of subarrays whose sum lies in the given range. Do so in less than O(n^2) complexity.
Given a number n, how to perform atmost k swap operations on number's digits to get the largest number. Ex- n=7899, k=2 ans=9987
Given an array of 3 different colored balls, we have to sort it using minimum number of swaps. It could be done in O(n) using 3-pointers and two traversals(one to count no. of occurrences of each color and other to sort). Could this be implemented in one traversal(count is not known before).
Link to problem:- http://www.codechef.com/problems/SUBARRAY
Link to solution:- http://www.codechef.com/viewsolution/7071035 Can anyone tell me the testcase my code gives wrong output for.
int main()
{
//Beauty is in relaxed hard work.
//SSGCA :)
//Keep doing your thing, complexity would turn into simplicity! :)
unsigned short int a=0xffff;
~a;
printf("%x",a);
return 0;
}
Why does this program output 'ffff' and not 0000?
Hey, could anyone please share problems on codeforces based on vertex cover problem. Thanks :)
The problem statement can be found here-> (http://www.codechef.com/DBYZ15/problems/DBYZ15C).
Why do many programmers use assert() function in their codes giving as its argument the answer to be outputed?
