Salary day

Bob Jones lives with his family. His family has $N$ members with

member IDs $O$ to $N-1.$ Bob Jones is the head of the family with

member ID $O.$ His family has $K$ number of earning members. Every

month, each earning member receives their salary in a particular

order and then gives it to their parent; the parent in turn gives the

salary to their parents, and so on$.$ The salary will be given to the

highest member of the family hierarchy. If member $A$ is the parent of

member $B$ and if A has already received the salary, then $B$ will keep

the salary.

For example, in the given family hierarchy $A>B>C,B$ is the parent of

A and $C$ is the parent of $B,$ so if A receives the salary, then it first

goes to $B,$ and then it goes to $C$ but in case if $C$ already had received

the salary then $B$ will keep the salary of A and if in case $B$ also

received the salary already then, A will keep the salary.

You are given two integers, $N$ and $K,$ where $N$ is the total number of

members in the family, and $K$ is the total number of earning members

in the family. You are given an array parents representing the parents

member ID$,$ where the index represents the child's member ID$.$ As

Bob Jones is the head of the family, he will have no parent that will

be represented by $-1,$ and therefore, the parent array will always start

with $-1.$ You are given an array salary$\_$order representing the member

IDs of all the earning members of the family in the order they receive

the salary that is index $O$ recelves the salary first and then index $1$ and

so on$.$

Return an array containing the member ID of all members that keep
