//  目前0位在座標[3,4]上面 將與位在座標[3,3]的20交換位置

============================================================================================== 

//  兩個數字0和20 成功執行位置交換的程式指令 目前0位在座標[3,3] 而20位在座標[3,4]

※數字推盤遊戲_進度：

「數字推盤遊戲」的規格不論是3X3,4X4,5X5…等，各種類型的推盤都符合一項要件，那就是他們都擁有一個1x1的空缺，好讓各個數字能藉著這個空缺穿梭在推盤的每個角落。而在我利用C Sharp所呈現的數字推盤遊戲中，數字0所象徵的正是那1x1的空缺。現在我已經成功讓推盤上的數字打亂了，所以接下來我們要面臨的難題就是該如何讓0周邊(上、下、左、右)的任意數字與0作“交換”的動作？
