mirrorSequence

Language/Type: Java recursion

Write a recursive method named mirrorSequence that accepts an integer parameter n and prints a sequence of n numbers as in the table below. For odd numbers the sequence has a single 1 in the middle, while for even values it has two 1s in the middle. Throw an IllegalArgumentException if passed a value less than 1.

Call Output
mirrorSequence(1); 1
mirrorSequence(2); 1 1
mirrorSequence(3); 2 1 2
mirrorSequence(4); 2 1 1 2
mirrorSequence(5); 3 2 1 2 3
mirrorSequence(6); 3 2 1 1 2 3
mirrorSequence(7); 4 3 2 1 2 3 4
mirrorSequence(8); 4 3 2 1 1 2 3 4
mirrorSequence(9); 5 4 3 2 1 2 3 4 5
mirrorSequence(10); 5 4 3 2 1 1 2 3 4 5
