![]() ![]() Jicfbaiducuk4LV# ![]() Jicfbaiducuk4LV# ![]() Jicfbaiducuk4LV Jicfbaiducuk4LV ![]() ![]() ![]() Jicfbaiducuk4LV{ Jicfbaiducuk4LV for( ![]() ![]() Jicfbaiducuk4LV { Jicfbaiducuk4LV ![]() ![]() Jicfbaiducuk4LV ![]() ![]() Jicfbaiducuk4LV { Jicfbaiducuk4LV pr ![]() Jicfbaiducuk4LV } Jicfbaiducuk4LV ![]() Jicfbaiducuk4LV { Jicfbaiducuk4LV pr ![]() Jicfbaiducuk4LV } Jicfbaiducuk4LV } Jicfbaiducuk4LV ![]() Jicfbaiducuk4LV} Jicfbaiducuk4LV Jicfbaiducuk4LV请问输出结果是什么? Jicfbaiducuk4LV Jicfbaiducuk4LV初看 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Jicfbaiducuk4LV Jicfbaiducuk4LV但是 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Jicfbaiducuk4LV1.i=0时 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Jicfbaiducuk4LV2.i=1时 ![]() ![]() ![]() ![]() Jicfbaiducuk4LV3.....过程于上面类似 ![]() ![]() ![]() ![]() ![]() ![]() Jicfbaiducuk4LV因此 ![]() ![]() ![]() ![]() Jicfbaiducuk4LV1 + 2 + 4 + ... + 2^(n - 1) = 2^n - 1 Jicfbaiducuk4LV Jicfbaiducuk4LV不过话说回来 ![]() ![]() ![]() ![]() ![]() ![]() Jicfbaiducuk4LV 0
