Chef has started learning about the stock market and has already selected a favourite stock.
He traded the stock for consecutive days. Let a_i denotes the profit earned by Chef on the -th day. Note that a_i < 0 indicates that Chef had a loss on the -th day.
Chef wants to find the maximum amount of profit he would have earned, if he skipped trading for exactly one day.
The first line contains the number of test cases t~(1 \le t \le 1000). The first line of each test case contains n~(1 \le n \le 10^5) — the number of days. The next line denotes integers a_i~(-100 \le a_i \le 100), denoting the profit earned by Chef on the -th day.
For each test case, print on a new line the maximum amount of profit he would have earned, if he skipped trading for exactly one day.
