获取大于或大于100的所有数组值，并获取小于100的数组所有值

def get_greater_than_or_equal_to_100(arr):
    result = []
    for num in arr:
        if num >= 100:
            result.append(num)
    return result

# 示例用法
arr = [50, 100, 150, 200, 250]
result = get_greater_than_or_equal_to_100(arr)
print(result)

def get_less_than_100(arr):
    result = []
    for num in arr:
        if num < 100:
            result.append(num)
    return result

# 示例用法
arr = [50, 100, 150, 200, 250]
result = get_less_than_100(arr)
print(result)
