Write a function to swap the adjacent characters of a string. Ex: "hello world" becomes "ehll oowlrd" void StringSwap(char *str); Predict the o/p of a recursive function. main(){ fib(5); } void fib(int m) { static int n=0; if(m==0) return; n++; fib(--m); printf(“%d %d\n”,m,n); } Write a function (recursive only) to find the largest element in an array of N numbers. int FindMax(int *array,int N); Write a function to insert an element in a singly list so that the elements are in descending order only. An integer array contains 1 to N unique natural numbers in any order. One of the element in the array is randomly choosen and overwritten by 0(zero) and it is sent as parameter to detectNum( ). Write a function to detect the number which was replaced by 0(zero).
