Count Array Element

题面

统计 32 位整数数组中等于给定整数 k 的元素个数，结果写入 output。

Implementation Requirements

• Use only native features (external libraries are not permitted)
• The solve function signature must remain unchanged
• 结果写入 output

Examples

Input: [1, 2, 3, 4, 1], k=1 → 2
Input: [5, 10, 5, 2], k=11 → 0

Constraints

• 1 ≤ N ≤ 100,000,000
• 1 ≤ input[i], k ≤ 100,000
• Performance: K = 501,010, N = 100,000,000
