the class np contains some problems that can be solved in polynomial time.
all of the problems in np can be solved in worst-case exponential time.
there are problems that can be reduced to the hamiltonian circuit problem and for which we have polynomial-time algorithms.

Allison and her group have completed the data entry for their spreadsheet project. they are in the process of formatting the data to make it easier to read and understand. the title is located in cell a5. the group has decided to merge cells a3: a7 to attempt to center the title over the data. after the merge, allison points out that it is not centered and looks bad. where would the title appear if allison unmerged the cells in an attempt to fix the title problem?
