Solution # 1
A simple and straightforward solution to this problem is to traverse through the array while computing and keeping track of the minimum absolute difference of each array element with the target number. Finally, you’ll return the element that has the minimum absolute difference.
Time Complexity
Since we have to go through each element one by one and compute its absolute difference, this solution is an ...
