Solution: Find K Closest Elements
Understand how to solve the problem of finding k closest elements to a target in a sorted array by exploring both naive and optimized algorithms. Learn to use modified binary search to locate the nearest element, then apply a two-pointer sliding window to select the closest k elements efficiently. This lesson guides you through time and space complexity analysis, alternative approaches, and implementation details.
Statement
You are given a sorted array of integers, nums, and two integers, target and k. Your task is to return k number of integers that are close to the target value, target. The integers in the output array should be in a sorted order.
An integer, nums[i], is considered to be closer to target, as compared to nums[j] when |nums[i] - target| |nums[j] - target|. However, when |nums[i] - target| |nums[j] - target|, the smaller of the two values is selected.
Constraints:
-
knums.length -
nums.length numsis sorted in ascending order.-
nums[i],target
