Problem 2 Suppose vou run a day care for an office building and there are seven children A,B,C,D,E.F,G. You need to assign a locker where each child's parent can put the child's food. The children come and leave so thev are not all there at the same time. You have 1 hour time slots starting 7:00 a.m. to 12:00 noon. A star in the table means a child is present at that time. What is the minimum number of lockers necessary? Show how you would assign the lockers The contention matrix of the problem is given below 07:00* 08:00*** 09:00'* 10:00 * 11:00* 12:00*
