For this question you will perform two levels of quicksort on an array containing these numbers:
59 41 61 73 43 57 50 13 96 88 42 77 27 95 32 89
In the first blank, enter the array contents after the top level partition.
In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition.
In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition.
Print the numbers with a single space between them.
Use the algorithm we covered in class, in which the first element of the subarray is the partition value.

- I selected a DC-DC converter capable of delivering 120 VDC from a 600 VDC input. When I reached out to the manufacturer, they asked for the total power consumption the converter would need to handle.To estimate this, I calculated the power requirements for the components that will use the 120 VDC supply: interior lighting, end lights, and buzzers. The breakdown is as follows:- Light Bulbs: 16 bulbs at 10 W each = 160 W- Buzzers: 2 buzzers at 5 W each = 10 W- End Lights: 2 lights at 15 W each = 30 W This results in a total estimated power demand of 200 W.My concern is whether I should request a higher wattage rating for the converter to provide sufficient tolerance and ensure the system operates efficiently without risking an overload.

- Using AutoCAD and exact measure that numberarrow_forwardA fully grouted reinforced masonry wall is to be constructed of 8-in. CMU. The wall height is 18feet. It is assumed to be simply supported. The wall is to be designed for an out-of-plane seismicload of 52 lbs./ft.2, which can act in either direction. The wall also supports a roof dead load of600 lbs./ft. and a roof live load of 300 lbs./ft. along the wall length. The roof loads have aneccentricity of 2.5 inches. Since there is seismic load, load combinations (6) and (7) in Chapter 2of ASCE 7-22 should be considered. In these two load combinations,horizontal seismic loadhE =andvertical seismic loadvE = .
