Count Occurrences

nums is sorted in non-decreasing order and may contain repeated values. Return how many times target appears.

Examples

Example 1

Input:

count_occurrences([1, 2, 2, 2, 3], 2)

Output:

3

Example 2

Input:

count_occurrences([1, 3], 2)

Output:

0

Constraints

• 0 <= len(nums) <= 2 * 10**5
• nums is sorted in non-decreasing order.
• -10**9 <= nums[i], target <= 10**9
• The big tests count how many values your code reads from the list (the limit is stated in the failure message). Reading every value, or using in, .index, .count, min or sorted on the whole list, fails them.
