Medium Data Structures > Basic Data Structures

**Sanvi** is a very cute girl. She likes chocolates so much. She has built a robot which provides her some amount of chocolates everyday. The robot operates **D** days consecutively. Everyday, It provides some amount of chocolates to Sanvi. You are given **Q** wishlist of Sanvi. Your task is to process her **Q** wishes. Every wish contain an integer denoting the total number of chocolates she wants to eat -**Y**. You have to find the total number of days required to fulfill her wish.Her wish will be fulfilled if she could get chocolates greater than or equal to **Y**. ***Note: Time limit is too tight. Naive solution will not pass within the time limit.*** Input: ------ Input starts with an integer **T (1<=T<=15)**, denoting the number of test cases. Each case starts with two integers **D,Q** as described in the problem statement. Then there will be a line with space separated **D** integers denoting amount of chocolate robot provide in each day( ***Ci*** ). Finally, There will be **Q** more lines with a integer ( ***Yi*** ) denoting amount of chocolate she wants to eat. Constraint: ------- **1<=D,Q,Ci,Yi<=10^5.** Output: ------- For every **Q** wishes output a line of output denoting total number of days required to fulfill that wish. If it is not possible to fulfill that wish, output **-1** instead. Sample Input ------------ 1 5 4 3 5 3 6 5 1 4 17 33 Sample Output ------------- 1 2 4 -1
