pls help!!!

C-4.45 page 185 ( 40 points): DO NOT SORT THE ARRAY. Must provide a test application with at least 2 sets of numbers. Hint: find smallest, largest, and sum. Compare the sum with the series summation. C-5.17 and C-5.18 page 222 (60 points): ASSUME STRINGS WITH NO PUNCTUATION ORSPACES. The test application should print the original string in reverse besides testing for palindrome. Hint: can use textbook example for reversing elements of an array on page 208. Your code should have appropriate class names, comments, and layout. Please submit all your code in compressed format (zip or rar). 4.45 An array A contains n1 unique integers in the range [0,n1], that is, there is one number from this range that is not in A. Design an O(n)-time algorithm for finding that number. You are only allowed to use O(1) additional space besides the array A itself. C.5.17 Write a short recursive Java method that takes a character string s and outputs its reverse. For example, the reverse of 'potsspans' would be 'snapkstop
