已知Python程序段：s1=""s2="123456"for i in range(-1,-6, -1):s1=s1+s2[i]print(s1)执行该段程序后输出的结果是（ ）。[/i]
举一反三
- 以下程序的输出结果是 String s1="1",s2="2"; String s=s1+s2; System.out.println(s);
- 有如下程序段：s = 0For i = 1 To 10 s = s + iNext iPrint s与上述程序段输出结果相同的程序段为( )。 A: s = 0: i = 0 While i <= 10 i = i + 1 s = s + i Wend Print s B: s = 0: i = 1 While i < 10 i = i + 1 s = s + i Wend Print s C: s = 0: i = 1 Do s = s + i i = i + 1 Loop While i < 10 Print s D: s = 0: i = 1 Do s = s + i i = i + 1 Loop Until i > 10 Print s
- 有一段程序: a = Array(1, 2, 3, 4, 5, 6): s =1: For i = 5 To 1 Step -2: s = s * a(i): Next I, 执行后，s的结果是
- 执行下列程序段后，程序的运行结果为()。 s = 1 For i = 1 To 3 For j = 0 To i - 1 s = s + s * j Next j Print s; Next i
- 16、下面程序的执行结果是______________。（1275） s = 0 for i in range(1,101): s += i if i == 50: print(s) break else: print(1)
