When I run the program, the below output comes.
{hi:9, mom:8, d:6, foo:3, ach:4, cbba:5, edf:7} null [hi:9] null [mom:8] [d:6] null [foo:3 ach:4 cbba:5] [edf:7]
how can I resolve this?
it shows the below output on the console.
{hi:9, mom:8, d:6, foo:3, ach:4, cbba:5, edf:7} null [hi:9] null [mom:8] [d:6] null [foo:3 ach:4 cbba:5] [edf:7]
It does not successfully run.
