For this test, you should define a struct named "node" containing 3 fields: int data int next int valid

*** These fields must be in the above order in the struct statement ***

Then write a function named "init" which accepts an array of nodes and performs the following initialization:

- for element[0], set valid=1, data=42 and next=-1 - for elements 1-99, set valid=0, data=999 and next=-99999

A prototype would be: void init(struct node*);
