struct Node $\{$

Bid bid;

unsigned int key;

Node $*$next;

$//$ default constructor

Node$()\{$

key $=$ UINT$\_$MAX;

next $=$ nullptr;

$\}$

$//$ initialize with a bid

Node$($Bid aBid$)$ : Node$()\{$

bid $=$ aBid;

$\}$

$//$ initialize with a bid and a key

Node$($Bid aBid, unsigned int aKey$)$ : Node$($aBid$)\{$

key $=$ aKey;

$\}$

$\}$;

vector nodes;

unsigned int tableSize $=$ DEFAULT$\_$SIZE;

unsigned int hash$($int key$)$;

const unsigned int DEFAULT$\_$SIZE $=179$;

double strToDouble$($string str$,$ char ch$)$;

struct Bid $\{$

string bidId; $//$ unique identifier

string title;

string fund;

double amount;

Bid$()\{$

amount $=0\mathrm{.}0$;

$\}$

$\}$;

Given these following fields and structures I need to complete all the tasks within their respective functions. Any help?
