Hey!

I was solving a problem on RMQ with the help of segment tree, but was consistently getting a SIGSEV error on submission. This was solved(gotAC) by making the size allocated for the segment tree to 6*n instead of 4*n. The segment tree implementation was a recursive one. Why did it need 6*n elements allocated since 4*n should be able to handle the worst case size.
