Create a file called maxSeq.c and write the function: + size_t maxSeq(int * array, size_t n); + + which returns the length of the maximum increasing contiguous + subsequence in the array. The parameter n specifies the length + of the array For example, if the array passed in were + + { 1, 2, 1, 3, 5, 7, 2, 4, 6, 9} + + this function would return 4 because the longest sequence + of (strictly) increasing numbers in that array is 1, 3, 5, 7 + which has length 4. Note that 1,3,5,7,9 is an increasing + subsequence, but is not contiguous (finding discontiguous + ones efficiently takes techniques we haven't learned yet). + + Note that the subseqence does not need to increase at a + constant rate (or follow any other pattern besides being strictly + increasing). 2, 4, 67, 93, 94, 102 would be a valid increasing + sequence of length 6. + + Also note that the series consisting of one element is considered an + increasing sequence of length 1. + + +2.
