條件，如果一個字節(jié)中1的中間有0,這樣的位也要被置1,
例如，
一個字節(jié)為：#01001100B轉(zhuǎn)化為#01111100B
謝謝了。
網(wǎng)友評論：待轉(zhuǎn)數(shù)據(jù)放在R7，轉(zhuǎn)完后放于ACC

網(wǎng)友評論：明天再來...
網(wǎng)友評論：實際中我的數(shù)是有12位的，我現(xiàn)在的做法就是先從左判斷，看判斷到第幾位為1,然后在從右判斷，判斷到第幾位為1.然后將它們中間的位全定義為1.

網(wǎng)友評論：來個總結(jié)，能否用程序的執(zhí)行時間與代碼長度的乘積作為評分標(biāo)準(zhǔn)？如果合理的話，呵呵41樓程序15*32=480比45樓程序12*41=492略勝一籌；不過我總覺得返回指令RET的時間不應(yīng)算在內(nèi)，因為過程完了，要返回是以后的事了。如果這樣算的話，45樓10*41=410又比41樓13*32=416優(yōu)勝一點~~~

傳感器，每個位表示一個傳感器，用來檢測輪胎寬度，１２個傳感器一字排開，當(dāng)測到哪幾個傳感器有效時判斷它們之間的寬度。我不像個位匯編高人，我只讓我的程序能正常運行，沒有你們那種力求完美的心。程序我也弄好了，就是先從左到右檢測，遇到１記下第幾位，在從右往左，遇到１記住第幾位。簡簡單單的實現(xiàn)，但對各位的佩服猶如滔滔江水連綿不絕....
