algorithm - Iterating through 2 maps preserving order on same line output

Question

I'm looking to iterate through 2 different maps, and have them output on a side by side basis like

foo --------- bar zoo--------- car

The problem stems from not being able to properly use 2 maps, although I dont have to use maps. the order of index doesnt matter but the key pair values must stay the same, so in this instance, zoo must be with car, but doesnt neccessarily have to be NEXT to foo bar,

for k, z := range teamA {
                    fmt.Fprintln(w, k+"  "+z)

                }
for k, z := range teamB {
                    fmt.Fprintln(w, k+"  "+z)

                }

But the error with this approach is it prints out all lines (each map has 5 values, so 10 lines total) in a block format like below, not side by side as i wish. How can I get it to print side by side? not like the block below

foo --- bar
zoo ------------ car

Answer 1

Preload keys from TeamB to an array. Then use a simple counter inside the range loop of TeamA to retrieve a key from an array and a corresponding value from TeamB

keys := make([]string, len(teamA))
i := 0
for k := range teamA {
                    keys[i] = k
                    i++
                }
i = 0
for k, z := range teamB {
                    kA := keys[i]
                    vA := teamA[k]
                    fmt.Fprintf(w, "%v%v%v%v", k, z, kA, vA)
                    i++
                }

If the sizes of maps are different, don`t forget to account for that.
