Problem Statement

You are given $N integers A_1, A_2, \dots, A_N$.
Also, define $B_i = A_i \times A_{i+1}$\ $(1 \leq i \leq N-1)$.
Print $B_1, B_2, \dots, B_{N-1}$ in this order, separated by spaces.

Input

The input is given from Standard Input in the following format:
N
$A_1 A_2 \dots A_N$

Output

Print $B_1, B_2, \dots, B_{N-1}$ in this order, separated by spaces.

Constraints

• $2 \leq N \leq 100$
• $1 \leq A_i \leq 100$
• All input values are integers.
