Suppose that each row of an n x n array A consist of 1's and 0's such that in any row of A, all the 1's come before any 0's in that row. Assuming A is already in memory, describe a method running in O(nlogn) time (not O(n2) times!) for counting the number of 1's in A.

Provide pseudo-code, correctness, and complexity analysis.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
