已知數據文件IN.dat中存有200個四位數，并已調用讀函數rData()把這些數存入數組a中，請編寫函數spellNum()，其功能是：把個位數字和千位數字重新組成一個新的二位數（新二位數的十位數字是原四位數的個位數字，新二位數的個位數字是原四位數的千位數字），以及把百位數字和十位數字組成另一個新的二位數（新二位數的十位數字是原四位數的百位數字，新二位數的個位數字是原四位數的十位數字），如果新組成的兩個二位數一個是奇數，另一個為偶數，并且兩個二位數中至少有一個數能被17整除，同時兩個新數的十位數字均不為0，則將滿足此條件的四位數按從大到小的順序存入數組b中，并要計算滿足上述條件的四位數的個數count。最后main()函數調用寫函數wData()，把結果count以及數組b中符合條件的四位數輸出到OUT.dat文件中。
