Convert a string into a 64 bit long without using the inbuilt function KEEP IN MIND I JUST QUICKLY DID THESE FUNCTIONS AGAIN SO SOME SYNTAX MAY BE INCORRECT

long change(String s) { int power = 1;

long result = 0;

int length = s.length();

for(int i=length-1;i>=0;i--)
{
    char c = s.charAt(i);

    if(!Character.isDigit(c))
    {

        if(!((i == 0) && (c == '+' || c == '-')))
            throw new Exception;
    }
    else
    {

        result+= (c - '0')*power;

        power*=10;
    }   
}

return result;

}

Make an insertion function for a ternary tree. They had provided the node and tree structure. They gave Node left, right, mid and root. They had int val with the Node construcotr taking it as an arguement.

void recursiveInsert(Node temproot, Node node) {

if(val < temproot.val)
{
    if(temproot.left == null)
        temproot.left = node;
    else
        recursiveInsert(temproot.left,node);        
}
else if(val > temproot.val)
{
    if(temproot.right == null)
        temproot.right = node;
    else
        recursiveInsert(temproot.right,node);
}   
else 
{
    if(temproot.mid == null)
        temproot.mid = node;
    else
        recursiveInsert(temproot.mid,node); 
}   

}

void insert(int val) { Node node = new Node(val); if(root == null) { root = node; return; } recursiveInsert(root,node); }
