The problem was: given the following prototype implement the function
void move( char** colNames, int toColumn, int fromColumn );
The function should move the column name at index fromColumn to the position toColumn. (It does not swap the columns.)
Now I just spent 43 min implementing this with a compiler and some trial and error.
During the interview I was expected to do it with pen and paper.
Now my IQ is above the 99th percentile but apparently there are people who can do this sort of thing in their head without errors and that's what some interviewers appear to be looking for. That's why this post hit home for me, though personally I probably wouldn't have had much trouble with linked lists.
