The problem statement:↵
↵
There is an array given of 1s and -1s and there is a distance K,the output required is the maximum no of pairs such that their sum is 0 and both the numbers are within K distance.↵
↵
eg:↵
for array:↵
↵
1 -1 1 -1 and K = 1 answer:2↵
↵
This can be done with brute force,but i think there would a more efficient algorithm than just brute force.Can anyone please suggest something better than,a pseudo code or is there any known algorithm for this?↵
↵
Edit:A number can be taken only once.↵
↵
Thanks.
