You are given an array nums
of positive integers and an integer k
.
In one operation, you can remove the last element of the array and add it to your collection.
\n\nReturn the minimum number of operations needed to collect elements 1, 2, ..., k
.
\n
Example 1:
\n\n\nInput: nums = [3,1,5,4,2], k = 2\nOutput: 4\nExplanation: After 4 operations, we collect elements 2, 4, 5, and 1, in this order. Our collection contains elements 1 and 2. Hence, the answer is 4.\n\n\n
Example 2:
\n\n\nInput: nums = [3,1,5,4,2], k = 5\nOutput: 5\nExplanation: After 5 operations, we collect elements 2, 4, 5, 1, and 3, in this order. Our collection contains elements 1 through 5. Hence, the answer is 5.\n\n\n
Example 3:
\n\n\nInput: nums = [3,2,5,3,1], k = 3\nOutput: 4\nExplanation: After 4 operations, we collect elements 1, 3, 5, and 2, in this order. Our collection contains elements 1 through 3. Hence, the answer is 4.\n\n\n
