A detachment of n soldiers must cross a wide and deep river with no bridge i sight. They notice two 12-year-old boys playing in a rowboat by the shore. The boat is so tiny, however, that it can only hold two boys or one soldier. How can the soldiers get across the river and leave the boys in joint possession of the boat? How many times need the boat pass from shore to shore?

A detachment of n soldiers must cross a wide and deep river with no bridge in
sight. They notice two 12-year-old boys playing in a rowboat by the shore. The boat is so
tiny, however, that it can only hold two boys or one soldier. How can the soldiers get
across the river and leave the boys in joint possession of the boat? How many times need
the boat pass from shore to shore?

thermostat, which will turn the heat on when the room temperature drops h degrees below its set point, Ts, and cuts heat off at a temperature h degrees higher than Ts . The system heats at a constant rate Q (thermal units per time unit), and the volume of the room is V, so, if the room were perfectly insulated, the heating system would raise the temperature of the room at the rate KVQ (degrees per time unit), where K is a constant of proportionality giving the change in temperature per thermal unit per unit volume. However, there is a heat loss to the outside that is proportional to the difference in temperature between the room and the outside. Using the modified Euler method, write a FORTRAN program to simulate this system, if the room temperature at time is T(t), T(0) = To, and the outside temperature, Tout' is given by: Case (1) : Tout is constant < Ts Case (2) : Tout = A sin(wt + 4)| , %3D reflecting daily cycles. A is temperature range, 2n/w is the period of a cycle, and o is the…

Legend has it that during the Jewish-Roman conflict, the first-century Jewish scholar Flavius Josephus was taken prisoner alongside a group of 40 fellow Jews. The captured troops made a decision to commit suicide rather than be caught and made plans to do so. To murder every third man until they were all dead, they were to surround the enemy in a circle. When Joseph and one other person decided they didn't want to participate, they rapidly estimated where they needed to be in the circle for survival. Create a programme that enables you to put n individuals in a circle and tell it to murder every m of them. The last individual in the group should be identified by number by the programme.
Four individuals wish to traverse an unstable bridge; they all start on the same side. You have 17 minutes to get everyone to the opposite side. Night has fallen, and they have only one torch. Two individuals may cross the bridge at once at most. Any crossing party, whether one or two individuals, must carry a torch. The torch must be carried back and forth; it cannot, for instance, be hurled. Person 1 crosses the bridge in one minute, person 2 in two minutes, person 3 in five minutes, and person 4 in ten minutes. A dyad must trek together at the slower individual's cadence. Create the algorithm specification that solves the problem.
In a classroom of 27 students, 11 students have a blue pen, 12 students have a red pen, 7 students carry both a blue pen and pencil, 5 students carry a pencil and a red pen, 4 students carry 2 pens - one red and one blue, 2 students come prepared with one of each type of writing utensil, and 3 students consistently come to class with nothing to write with on paper and borrow from their study buddy. How many students carry only a pencil?
Three guys John, Paul and Peter are on a death row in GA. Governor decided to pardon one of them randomly chosen. He told the name of the pardoned to the gourd. Night before execution, each prisoner is in his own cell and none are supposed to knowwho will be pardoned. John asks the guard to give him the name from the other two who will be executed. Guard answers that Peter will be executed. John gets happier - before the guard gave him the name, his probability to survive was 1/3, and now when he knows that either him or Paul will be pardoned, his probability to survive is higher = 1/2. Is it correct? Should John be happy?(Give YOUR EXPLANATION for the probabilities for John to be pardoned))
Suppose you are provided an even number of people going on an adventure, and there are only two-seated rafts. All rafts are identical, weighing 20kg each. Each person is described by two parameters, their strength and weight. The speed of a raft can be calculated as the sum of strengths of both persons sitting in it, divided by the total weight of the loaded. We would like to choose the allocation of people to rafts so as to maximize the speed at which the whole group can travel, assuming that the group travels at the speed of the slowest raft in it. Develop a python code to find the maximum speed of the group which can be achieved by optimally choosing places for each person.
