Victor has an array of size n.He loves to play with these n numbers.each time he plays with them ,he picks up any two consecutive numbers and adds them. on adding both numbers, it costs him K*(sum of both numbers).
Find the minimum cost of adding all the numbers in the array.
i/p1:size of array
i/p2:elements of array
i/p3:value of K
o/p:return the maximum cost of adding all the numbers of the array.
Ex1:
i/p1:3
i/p2:{1,2,3}
i/p3:2
o/p:18
1500kg of steam is to be produced per hour with an enthalpy of 3077kj/kg. The feed water supplied to the boiler has an enthalpy of 167.5 kj/kg. The velocities of the water at inlet and the steam at exist are 2m/s and 45m/s respectively. Find the rate of which heat must be supplied to the boiler.
