Maximums
Alicia has an array, a_1, a_2, …, a_n, of non-negative integers. For each 1 ≤ i ≤ n, she has found a non-negative integer x_i = max(0, a_1, …, a_{i-1}). Note that for i=1, x_i = 0.
For example, if Alicia had the array a = {0, 1, 2, 0, 3}, then x = {0, 0, 1, 2, 2}.
Then, she calculated an array, b_1, b_2, …, b_n: b_i = a_i - x_i.
For example, if Alicia had the array a = {0, 1, 2, 0, 3}, b = {0-0, 1-0, 2-1, 0-2, 3-2} = {0, 1, 1, -2, 1}.
Alicia gives you the values b_1, b_2, …, b_n and asks you to restore the values a_1, a_2, …, a_n. Can you help her solve the problem?
Input
The first line contains one integer n (3 ≤ n ≤ 200 000) – the number of elements in Alicia's array.
The next line contains n integers, b_1, b_2, …, b_n (-10^9 ≤ b_i ≤ 10^9).
It is guaranteed that for the given array b there is a solution a_1, a_2, …, a_n, for all elements of which the following is true: 0 ≤ a_i ≤ 10^9.
Output
Print n integers, a_1, a_2, …, a_n (0 ≤ a_i ≤ 10^9), such that if you calculate x according to the statement, b_1 will be equal to a_1 - x_1, b_2 will be equal to a_2 - x_2, ..., and b_n will be equal to a_n - x_n.
It is guaranteed that there exists at least one solution for the given tests. It can be shown that the solution is unique.

Note
The first test was described in the problem statement.
In the second test, if Alicia had an array a = {1000, 1000000000, 0}, then x = {0, 1000, 1000000000} and b = {1000-0, 1000000000-1000, 0-1000000000} = {1000, 999999000, -1000000000}.
