DSA Level 2 Arrays and Strings Searching and Sorting Find First And Last Postion Of Element In Sorted Array

Find First And Last Postion Of Element In Sorted Array

easy

1. Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value.
2. If target is not found in the array, return [-1, -1].
3. You must write an algorithm with O(log n) runtime complexity.
