}あとappendの取扱については、これなど
// 後半部の処理
sliceX1 = sliceZ[0]
base_a = sliceZ[0][i]
sliceX2 = append(sliceX1[:i], sliceX1[i+1:]...) // i番目の要素を削除
//fmt.Println("A:sliceX2:", sliceX2[0:10], sliceX2[10:20], sliceX2[20:30], sliceX2[30:90])
sliceX2 = append(sliceX2[:31], sliceX2[30:]...) // i番目の要素を先頭に挿入
//fmt.Println("B:sliceX2:", sliceX2[0:10], sliceX2[10:20], sliceX2[20:30], sliceX2[30:90])
sliceX2[30] = base_a
//fmt.Println("C:sliceX2:", sliceX2[0:10], sliceX2[10:20], sliceX2[20:30], sliceX2[30:90])
sliceZ[0] = sliceX2
//fmt.Println("D:", sliceZ[0][0:10], sliceZ[0][10:20], sliceZ[0][20:30], sliceZ[0][30:90])
//fmt.Println()
