Consider an array with n elements and value of all the elements is zero. We can perform following operations on the array. 
 
1. Incremental operations:Choose 1 element from the array and increment its value by 1.
2. Doubling operation: Double the values of all the elements of array.

Input: target[] = {2, 3}
Output: 4
To get the target array from {0, 0}, we 
first increment both elements by 1 (2 
operations), then double the array (1 
operation). Finally increment second
element (1 more operation)

Given a number x, determine whether the given number is Armstrong number or not.

Input : 153
Output : Yes
153 is an Armstrong number.
1*1*1 + 5*5*5 + 3*3*3 = 153

Input : 120
Output : No
120 is not a Armstrong number.
1*1*1 + 2*2*2 + 0*0*0 = 9

You need to print
Odd Occurence of the number in order of their occurrence
Counting of number is regardless of magnitude

testcase 1
n = 15
Array = { 10, 0, 1, -1, 10, 7, -8, 9, -7, 2, 9, 3, 8, 8, -9 }
output = 0 -8 9 2 3

testcase 2
n = 17
Array = { 2, -12, 0, 12, 1, 8, 10, -2, 19, 7, 7, -7, -19, 5, 2, 0, 12}
output = 2 -12 1 8 10 7 5
