The second test is wrong. 4 is not < 1.
The example seems to be wrong as well. The output should be 9 (as stated in test 1 which uses the same vector), not 7.
thanks Sean and Jon for comment on problem, I have corrected the same.
this is a test case specific solution and would not work if change the test cases.
