某查找算法的部分VB代码如下: shifouzhaodao = False ‘shifouzhaodao:是否找到
szysxh = 0 ‘szysxh:数组元素序号
Do While szysxh < 5 And not shifouzhaodao
szysxh = szysxh + 1
if dczsz(szysxh) = Key then shifouzhaodao = true
Loop
if not shifouzhaodao then szysxh = 0
数组元素dczsz (1)到dczsz (5)的数据依次为“-1,3,7,10,7”,当变量key值为7时,运用该算法处理后,变量i的值是( )
