The contest can be explained with certain sample inputs and outputs * * * * Example 1: a clear sequence without any error * * I.1 = 8 I.2 = 5 -3 2 -1 1 0 1 1 * * O.1 = 0 O.2 = * * Description : need an error element * * * * Example 2: a correct sequence of 4 or more in middle without any error * * I.1 = 8 I.2 = 2 3 -6 4 -2 2 0 7 * * O.1 = 2 O.2 = 1 6 2 7 * * Description : changing first and last element to correct sequence * * 10(3) -6 4 -2 2 0 and -6 4 -2 2 0 2(7) * * * * Example 3: Second and 4th element incorrect * * I.1 = 8 I.2 = 1 5 8 12 19 31 71 81 * * O.1 = 2 O.2 = 1 5 3 7 * * Description : 5 7(8) 12 19 31 and 12 19 31 50(71) 81 * * * * Example 4: Consecutive elements incorrect in two sequences * * I.1 = 9 I.2 = 2 7 -5 2 -4 -1 2 8 10 * * O.1 = 2 O.2 = 1 5 4 8 * * Description : 7 -5 2 -3(-4) -1 and -4 6(-1) 2 8 10 * * * * The tests would cover many more complex cases * * The encoding should be as above
