Finding a First Occurrence

Given a sorted array of integers 'nums' and an integer 'target', return the index of the first occurrence of 'target' in 'nums'. If 'target' is not present, return -1. Input format: - The first line contains an integer n (1 ≤ n ≤ 10^5), the number of elements in the array. - The second line contains n space-separated integers, the elements of the array (0 ≤ nums[i] ≤ 10^9). - The third line contains a single integer target (0 ≤ target ≤ 10^9). Output format: - Print a single integer, the index of the first occurrence of target or -1 if not found. Example: Input: 5 1 2 2 2 3 2 Output: 1
