While determining the peak of the mountian array if the peak is found out at last or first element then shouldn’t we return -1 indicating that the peak for that array can’t be found ?
The solution includes the condition for finding peak at last element into the solution but shouldn’t it be like this
if(mid == nums.length - 1 || mid == 0 ) return -1;
