An array with 150 unique elements is subscripted starting with 0. you would like to iteratively use partition to find the thirty largest values, but there is no requirement that the thirty largest values be ordered. which of the following is not correct?
a. if 119 is returned from partition, we must continue.
b. if 118 is returned from partition, we must continue.
c. if 131 is returned from partition, we must continue.
d. if 120 is returned from partition, we are done.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
