Write a recurrence to count the number of comparisons made by STRAIGHTEN on an array of size n. Write a recurrence to count the number of comparisons made by WEIRDSORT on an array of size n. Solve these two recurrences to obtain an asymptotic expression for the number of comparisons done by STRAIGHTEN and by WEIRDSORT. No need to show your calculations.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
