3.Four men are walking late at night. Together they have one flashlight with a weak battery, so that it can only light the immediate vicinity. They come to a bridge, which is so rickety that only two can cross at the same time. Thus, in order to get to the other end of the bridge, two must cross with the flashlight and one must walk back across the bridge to return the flashlight (they cannot risk throwing it), until all are over. The men can walk at different maximum rates. The slowest needs 10 minutes to cross the bridge, the next 5 minutes, the next 2 minutes and the quickest 1 minute. When two walk together, they must proceed at the pace of the slower. They need to get everyone across the bridge in 17-minutes. Can they do it? How?

Solve each of the following problems using the problem solving strategies.
1.This is known as the "Die Hard Problem" because it appears in the film Die Hard with a Vengeance, shown in 1995. But in fact, this and other similar problems. are very old and have been the subject of much study, particularly by computer scientists who have developed various strategies for solving all water-jug problems. In the film, the characters played by Bruce Willis and Samuel L. Jackson must disarm a bomb by placing exactly four gallons of water on a scale. They have water since they are at a fountain, but they have only two jugs, one of which holds five gallons and the other three gallons. Can you solve the problem, and how quickly can you do it?

Write a program to overload operators in the same program by writing suitable operator member functions for following expression:
O7= ((O1 % O2)>(O3 || O4) - (O5>O6)) [Here O1,O2,O3,O4,O5,O6 and O7 are objects of a class “overloading”, and this class is having one integer data member]
