使用lambda填充向量以确定索引是偶数还是奇数

vector = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# 使用lambda函数填充向量
filled_vector = list(map(lambda x: x if x % 2 == 0 else -x, vector))

# 确定索引是偶数还是奇数
index_type = list(map(lambda x: "even" if x % 2 == 0 else "odd", range(len(vector))))

print("Filled Vector:", filled_vector)
print("Index Type:", index_type)

Filled Vector: [-1, 2, -3, 4, -5, 6, -7, 8, -9, 10]
Index Type: ['even', 'odd', 'even', 'odd', 'even', 'odd', 'even', 'odd', 'even', 'odd']
