The moving average of a numeric sequence is a sequence of averages of subsequences of the original sequence; the subsequences are known as windows (or a sliding window), and the length of the subsequence used is called the window size. More precisely, given a sequence s, the moving average with window size w is sequence A such that the first element in A is the average of w consecutive elements in s starting with the first, the second element in A is the average of w consecutive elements in s starting with the second, and so on until the last element in A, which is the average of w consecutive elements in s ending with the last. Example: If s [2, e, -2, 2] and w = 2, the moving average is [1, -1, 0]. 1 is the average of [2, 0], 1 is the average of e 2], and e is the average of [-2, 2] Write a function moving_average(seq, wsize) that computes and returns the moving average of seq with window size wsize
