What value will the f(4) return from the following recursive function?                 int f( int x )                 {                                 if( x == 0 )

T/F 9) Since iterative solutions often use loop variables and recursive solutions do not, the recursive solution is usuallymore memory efficient (uses less memory) than the equivalent iterative solution

Data Structures and Algorithms in C/C++ a) Implement the addLargeNumbers function with the following prototype: void addLargeNumbers(const char *pNum1, const char *pNum2); This function should output the result of adding the two numbers passed in as strings. Here is an example call to this function with the expected output: /* Sample call to addLargeNumbers */ addLargeNumbers("592", "3784"); /* Expected output */ 4376 b)  Implement a test program that demonstrates adding at least three pairs of large numbers (numbers larger than can be represented by a long). c) (1 point) Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant.

plz can you explain this for me thanks

Question 31 Below is a recursive version of binary search, which was not presented in class. When calling this method (from the main or other method) what would need to be passed as actual parameters? 1) public static int binarySearch(intO a, int hi, int low, int mid, int x) { 2) if (low > hi) 3) return -1; 4) else if (a[mid] x). return mid; else if (x < a[mid]) return binarySearch(a,mid-1,low, (low+mid-1)/2,x); else return binarySearch(a,hi,mid+1, (mid+1+hi)/2,x); 10) } first parameter - an array to be searched second parameter - the length of the array minus 1 O third parameter - 0 forth parameter - (n-1)/2, where n is the length of the array O fifth parameter - the integer to be searched for O all of the above

Consider the following recursive method:   Public static int Fib(int a1, int a2, int n){   if(n == 1)      return a1;   else if (n == 2)      return a2;else      return Fib(a1, a2, n-1) + Fib(a1, a2, n-2);} Please draw the recursion trace for Fib(2,3,5)

a) Write a recursive method that calculates the following series:F(n)= (??+Σ?)??=1*(??+Σ?)?/??=1*(??+Σ?)?/??=1*(??+Σ?)?/??=1*….*2b) Write the recurrence expression T(n).

int getMax(int arr[], int n) { intmx=arr[0]; for (inti=1; i<n; i++) if (arr[i] >mx) mx=arr[i]; returnmx; }   Can u give me the code for this one as well....this is the first function and countsort is the second

It is suspected that out of a set of 64 50p coins one of the coins is fake (i.e., lighter in weight than a genuine coin). With one weighing scale. (i)Give a detailed explanation on how you would go about determining the fake coin. (ii)What is the minimum number of times you need to use the scales to weigh the coins before identifying the fake coin?    (iii)Write a recursive method that returns the value of N! (N factorial). Explain why you would not normally use recursion to solve this problem.
