Find index of closest value in array python

WebJan 31, 2024 · An Optimized Solution is to find k elements in O (Logn + k) time. The idea is to use Binary Search to find the crossover point. Once we find index of crossover point, we can print k closest elements in O (k) time. The time complexity of this method is O (Logn + k). Auxiliary Space :O (1) , since no extra space has been used.
