Calculate the complexity t(n) of the bubble-sort algorithm below. calculate the constant cost of a step by assuming that each basic operation included in that step – addition, subtraction, multiplication, division, array-read, array-write, assigning a value to a variable, returning a value, etc. – has a cost of 1. so the cost of executing a statement once is to be calculated as the total number of basic operations that have to be executed. fill in the table below, then determine the expression for t(n) and simplify it to produce a polynomial in n. in the second column for steps 4-9, provide sigma (summation) notation.
