{ "data": { "question": { "questionId": "3331", "questionFrontendId": "3065", "categoryTitle": "Algorithms", "boundTopicId": 2658935, "title": "Minimum Operations to Exceed Threshold Value I", "titleSlug": "minimum-operations-to-exceed-threshold-value-i", "content": "
You are given a 0-indexed integer array nums
, and an integer k
.
In one operation, you can remove one occurrence of the smallest element of nums
.
Return the minimum number of operations needed so that all elements of the array are greater than or equal to k
.
\n
Example 1:
\n\n\nInput: nums = [2,11,10,1,3], k = 10\nOutput: 3\nExplanation: After one operation, nums becomes equal to [2, 11, 10, 3].\nAfter two operations, nums becomes equal to [11, 10, 3].\nAfter three operations, nums becomes equal to [11, 10].\nAt this stage, all the elements of nums are greater than or equal to 10 so we can stop.\nIt can be shown that 3 is the minimum number of operations needed so that all elements of the array are greater than or equal to 10.\n\n\n
Example 2:
\n\n\nInput: nums = [1,1,2,4,9], k = 1\nOutput: 0\nExplanation: All elements of the array are greater than or equal to 1 so we do not need to apply any operations on nums.\n\n
Example 3:
\n\n\nInput: nums = [1,1,2,4,9], k = 9\nOutput: 4\nExplanation: only a single element of nums is greater than or equal to 9 so we need to apply the operations 4 times on nums.\n\n\n
\n
Constraints:
\n\n1 <= nums.length <= 50
1 <= nums[i] <= 109
1 <= k <= 109
i
such that nums[i] >= k
.给你一个下标从 0 开始的整数数组 nums
和一个整数 k
。
一次操作中,你可以删除 nums
中的最小元素。
你需要使数组中的所有元素都大于或等于 k
,请你返回需要的 最少 操作次数。
\n\n
示例 1:
\n\n\n输入:nums = [2,11,10,1,3], k = 10\n输出:3\n解释:第一次操作后,nums 变为 [2, 11, 10, 3] 。\n第二次操作后,nums 变为 [11, 10, 3] 。\n第三次操作后,nums 变为 [11, 10] 。\n此时,数组中的所有元素都大于等于 10 ,所以我们停止操作。\n使数组中所有元素都大于等于 10 需要的最少操作次数为 3 。\n\n\n
示例 2:
\n\n\n输入:nums = [1,1,2,4,9], k = 1\n输出:0\n解释:数组中的所有元素都大于等于 1 ,所以不需要对 nums 做任何操作。\n\n
示例 3:
\n\n\n输入:nums = [1,1,2,4,9], k = 9\n输出:4\n解释:nums 中只有一个元素大于等于 9 ,所以需要执行 4 次操作。\n\n\n
\n\n
提示:
\n\n1 <= nums.length <= 50
1 <= nums[i] <= 109
1 <= k <= 109
nums[i] >= k
的下标 i
存在。nums
and count the number of elements less than k
