Integer Issue with LongestIncreasingSubsequence.java

[hollowthought]

Hey I found an issue with your code LongestIncreasingSubsequence.java

Line 18: int mid = (int) Math.ceil((low + high)/2);

The Ceiling algorithm won't have any effect because the decimal portion is already truncated.
Changing 2 to 2.0 will force the quotient to be a floating point.

int mid = (int) Math.ceil((low + high)/2.0);
