I was trying to apply the divide and conquer algorithm for closest pair of points on this problem. I have been getting wrong answer many times. My solution is here. I read this algorith from this site.
You are running out of memory. Use vector instead of array with size 50k in line #99. Btw. it is not implemented optimally (complexity is with log^2 I think). I suggest you check out this algorithm with set. It is much simpler.
In 23-rd line you multiply ints up to 106. It will cause overflow. And be careful about number of digits in output.
I corrected the overflow situation but again I am getting segmentation fault. Could you please check it again? My new solution is here

For example consider test where all points have the same x-coordinate. Then your program is . It can be fixed but it's nothing fun.
I fixed the size of that array to n everytime. Got accepted now. Thanks bro.
