Max Minus Min

You are given an array $A$ of $N$ integers. You can perform the following operation as many times as you want (possibly $0$): - Choose index $i$ ($1 \le i \le N$), and multiply $A_i$ by $2$. Find the **minimum** possible value of $\max(A) - \min(A)$ you can achieve through the use of the operations. ### Input - The first line of input will contain a single integer $T$, denoting the number of t
