+ 1. 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. Compile and test your code using the test-subseq.c you wrote
+ previously. (as before, compile the .c files separately, and link
+ them together).
+
+3. Submit your code for maxSeq.c
+
+
+Hint:
+ Can you abstract a complex step out into a simple function?
