Question

7. Complete the body y of digitAppears so it satisfies its contract. For full credit, you must use only kernel methods, recursion and one return statement For example, if n 1234, digitAppears(n, 4) returns true. Reports if digit appears in n when it is wnitten in ordinary decimal ensures digitappears- [if the digit digit appears in n) " notation. private static boolean digitAppears (NaturalNumber n, int digit)( 8 Complete the body of longest Text so it satisfies its contract. For full credit, you must use recursion and only one return statement Reports the text of the longest plain text node in the XMLTree t. eparam t @return the text of the longest plain text node in t the XMLTree * grequires [t has at least one plain text node] * gensures longest Text [the text of the longest plain text node in t] private static String longestText (xMLTree t) f

Explanation / Answer

If you post more than 1 question, as per chegg guideines I have to solve only 1 question.

Ques 7.

private static boolean digitAppears(NaturalNumber n, int digit)

{

    while( n > 0 )

    {

        // if the digit at ones place is same as digit

        if( n % 10 == digit )

            return true;

       

        // remove the digit at ones place

        n = n / 10;

    }
