我正在尝试构建这个b +树而无法做到这一点。 2阶树(4个最大节点和2个最小值)应具有以下条目23,65,37,60,46,92,48,71,56,59,18,21,10,74,78,15 ,16,20,24,28,39,43,47,50,69,75,8,49,33,38。

这就是我得到的:

Root:46

第一级:{28,46,60}

第二级:L1 = {15,18,23},L2 = {37,39},L3 = {48,56},L4 =​​ {71,78}

第3级:L11 = {8,10},L12 = {15,16},L13 = {18,20,21},L14 = {23,24},L21 = {28,33},L22 = {37,38},L23 = {39,43},L31 = {28,33},L32 = {37,38},L33 = {39,43},L41 = {60,65,69},L42 = {71,74,75},L43 = {78,92}

如果我犯了任何错误,请告诉我。

这对我来说不合适。

你可以watch the tree getting generated。结果如下:
