WebGiven a shifted array of sorted unique integers, write a function findTargetIndex that returns the index of a target value. You are given an array of sorted integers that has been shifted by an unknown number of spots. For example: Original array: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] Shifted array: [3, 4, 5, 6, 7, 8, 9, 0, 1, 2] WebShifted Array Search A sorted array of distinct integers shiftArr is shifted to the left by an unknown offset and you don’t have a pre-shifted copy of it.
