附件prog.txt 中是一个用某种语言写的程序。 其中REPEAT k 表示一个次数为k 的循环。循环控制的范围由缩进表达, 从次行开始连续的缩进比该行多的(前面的空白更长的)为循环包含的内容。 例如如下片段: REPEAT 2: A = A + 4 REPEAT 5: REPEAT 6: A = A + 5 A = A + 7 A = A + 8 A = A + 9 该片段中从A = A + 4 所在的行到A = A + 8 所在的行都在第一行的 循环两次中。 REPEAT 6: 所在的行到A = A + 7 所在的行都在REPEAT 5: 循环中。 A = A + 5 实际总共的循环次数是2 * 5 * 6 = 60 次。 请问该程序执行完毕之后,A 的值是多少?
就一句话
