从数组中提取信息的双循环

# 示例代码（Python）

# 定义一个包含多个数组元素的示例数组
array = [1, 2, 3, 4, 5]

# 外部循环遍历数组的每个元素
for i in range(len(array)):
    # 内部循环用于在每个元素上执行特定操作
    for j in range(i+1, len(array)):
        # 在这里可以执行特定的操作，例如比较元素大小、计算元素之间的差值等
        difference = array[j] - array[i]
        print(f"The difference between {array[j]} and {array[i]} is {difference}")

# 输出结果：
# The difference between 2 and 1 is 1
# The difference between 3 and 1 is 2
# The difference between 4 and 1 is 3
# The difference between 5 and 1 is 4
# The difference between 3 and 2 is 1
# The difference between 4 and 2 is 2
# The difference between 5 and 2 is 3
# The difference between 4 and 3 is 1
# The difference between 5 and 3 is 2
# The difference between 5 and 4 is 1
