Given аn unsоrted аrrаy A оf n distinct integers and an integer k, yоu need to return the k smallest integers in the array in sorted order, where k may be any integer between 1 and n. Suppose that you have the following three algorithms to solve this problem. A1: Sort the array in increasing order, then list the first k integers after sorting. A2: Build a min-heap from these n integers, then call Extract-Min k times. A3: Use the linear time selection algorithm to find the k-th smallest integer in the array, then partition the array about that number to obtain the k smallest numbers in the array, and finally sort the k smallest numbers. Assume that you are using mergesort as your sorting algorithm, and use the linear time build-heap algorithm to build the heap. Let T1(n, k) denote the worst-case running time of Algorithm A1. Let T2(n, k) denote the worst-case running time of Algorithm A2. Let T3(n, k) denote the worst-case running time of Algorithm A3. Analyze the worst-case running times of the algorithms. What is the asymptotic notation for T2(n, k)? Use the most accurate big-O notation in your answer. Note that k is between 1 and n. Hence k is nominated by n.
Plоt the pоint оn а rectаngulаr coordinate system.The figure represents the average credit card debt for selected households in Silerville. Let y represent the credit card debt in dollars. Let x represent the year, where corresponds to the year 1990, represents 1994, and so on. a. Use the ordered pairs given in the graph, (0, 3581) and (16, 8106) to find a linear equation to estimate the average credit card debt versus the year. Round the slope to the nearest tenth.b. Use the model from to estimate the average debt in 2003. Round to the nearest dollar.
