[BUG] Python output issue

[DevonStee]

My local Python environment is configured correctly, and executing other Python code works fine, but it seems to enter an infinite loop when executing this code.

class Solution:
  def getPairsCount(self, process: List[int], k: int) -> int:
    ans = 0
    n = len(process)
    process.sort()
    j = 0
    for i in range(n):
      while j < n:
        if process[j] - process[i] <= k:
          j += 1

        else:
          ans += j - i
          break
    return ans

a = Solution()
process = [100, 200, 300, 400]
k = 250
print(a.getPairsCount(process,k))
