B+ Tree builbing from scratch

Question

I've being trying to build this b+ tree and was unable to do it. the tree of order 2 (4 maximum nodes & 2 minimum) should have the following entries 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.

This is what I got:

Root: 46

1st Level: {28,46,60}

2nd Level: L1={15,18,23}, L2={37,39}, L3= {48,56}, L4= {71,78}

3rd Level: 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}

Please let me know if I made any mistakes.
