i have [["a", "b", "c"],["a", "b", "z"],["d", "e", "f"],["d", "e", "p"]]

ok i need to buil {a=>??,d=>??}
THEN i need to build {a=>b, d=>e}
THEN i need to build {a=>{b=>??},d=>{e=>??}}
THEN i need to build {a=>{b=>[]]},d=>{e=>[]]}}

** maybe make [c,z] and [f,p]

THEN i need to build {a=>{b=>[c]]},d=>{e=>[f]]}}
THEN i need to build {a=>{b=>[c,z]]},d=>{e=>[f,p]]}}

i want {a=>{b=>[c,z]}, d=>{e=>[f,p]}}


i have {a=>{b=>[c,z,f,p]]},d=>{e=>[c,z,f,p]]}}
