We have to complete a total of ‘N’ works. Now, each work can be done on only one of the two special days given in 2 different arrays ‘day1’ and ‘day2’ respectively.

day1[i] denotes that the ‘i-th’ work can on the day1[i] th day and day2[i] denotes that the ‘i-th’ work can on the day2[i] th day. Also, it is guaranteed that day2[i] < day1[i].

Also, make sure, the works are being done in such a way that they must be in non-decreasing order in terms of days given in array ‘day1’.

Your task is to find the minimum number of days in which all the work can be completed.

For example

day1 = {5, 6, 2}
day2 = {2, 4, 1}

In this case, the ideal order will be to perform work 3 on the first day, work 1 on the second day and work 2 on the fourth day. The order with respect to Day1 in which the work is done will be {2, 5, 6} which is non-decreasing. Hence the number of days needed to finish all work will be 4.

Given two candles. Each of them burns for one hour. They burn unevenly in different parts though. In addition, let’s have a box of matches. Measure 45 minutes and 15 minutes.
