The task is to print the number of unique subsequences possible of length K. There is a well-known formula for how many subsequences of fixed length K can be chosen from N unique objects. Where am I going wrong? For such a problem there can be no ready combinatorics formula because the results depend on the order of the original array. Can I change which outlet on a circuit has the GFCI reset switch? But length of the string is 13 so i<=s.length means i<=13 loop runs 14 times and the substring indexes Space complexity: O(1).
