You are given an array nums
consisting of positive integers.
You are also given an integer array queries
of size m
. For the ith
query, you want to make all of the elements of nums
equal to queries[i]
. You can perform the following operation on the array any number of times:
1
.Return an array answer
of size m
where answer[i]
is the minimum number of operations to make all elements of nums
equal to queries[i]
.
Note that after each query the array is reset to its original state.
\n\n\n
Example 1:
\n\n\nInput: nums = [3,1,6,8], queries = [1,5]\nOutput: [14,10]\nExplanation: For the first query we can do the following operations:\n- Decrease nums[0] 2 times, so that nums = [1,1,6,8].\n- Decrease nums[2] 5 times, so that nums = [1,1,1,8].\n- Decrease nums[3] 7 times, so that nums = [1,1,1,1].\nSo the total number of operations for the first query is 2 + 5 + 7 = 14.\nFor the second query we can do the following operations:\n- Increase nums[0] 2 times, so that nums = [5,1,6,8].\n- Increase nums[1] 4 times, so that nums = [5,5,6,8].\n- Decrease nums[2] 1 time, so that nums = [5,5,5,8].\n- Decrease nums[3] 3 times, so that nums = [5,5,5,5].\nSo the total number of operations for the second query is 2 + 4 + 1 + 3 = 10.\n\n\n
Example 2:
\n\n\nInput: nums = [2,9,6,3], queries = [10]\nOutput: [20]\nExplanation: We can increase each value in the array to 10. The total number of operations will be 8 + 1 + 4 + 7 = 20.\n\n\n
\n
Constraints:
\n\nn == nums.length
m == queries.length
1 <= n, m <= 105
1 <= nums[i], queries[i] <= 109
给你一个正整数数组 nums
。
同时给你一个长度为 m
的整数数组 queries
。第 i
个查询中,你需要将 nums
中所有元素变成 queries[i]
。你可以执行以下操作 任意 次:
1
。请你返回一个长度为 m
的数组 answer
,其中 answer[i]
是将 nums
中所有元素变成 queries[i]
的 最少 操作次数。
注意,每次查询后,数组变回最开始的值。
\n\n\n\n
示例 1:
\n\n输入:nums = [3,1,6,8], queries = [1,5]\n输出:[14,10]\n解释:第一个查询,我们可以执行以下操作:\n- 将 nums[0] 减小 2 次,nums = [1,1,6,8] 。\n- 将 nums[2] 减小 5 次,nums = [1,1,1,8] 。\n- 将 nums[3] 减小 7 次,nums = [1,1,1,1] 。\n第一个查询的总操作次数为 2 + 5 + 7 = 14 。\n第二个查询,我们可以执行以下操作:\n- 将 nums[0] 增大 2 次,nums = [5,1,6,8] 。\n- 将 nums[1] 增大 4 次,nums = [5,5,6,8] 。\n- 将 nums[2] 减小 1 次,nums = [5,5,5,8] 。\n- 将 nums[3] 减小 3 次,nums = [5,5,5,5] 。\n第二个查询的总操作次数为 2 + 4 + 1 + 3 = 10 。\n\n\n
示例 2:
\n\n输入:nums = [2,9,6,3], queries = [10]\n输出:[20]\n解释:我们可以将数组中所有元素都增大到 10 ,总操作次数为 8 + 1 + 4 + 7 = 20 。\n\n\n

提示:
\n\nn == nums.length
m == queries.length
