- Implement two methods (using iterative and recursive approaches) to compute the sum of the reciprocals of the first n natural numbers. Mathematically, it can be denoted as follows: Sum(n) = 1 + 1 2+1 3+ ... + 1 n (1) Example 1: Input: [1] Output: [1.0] Explanation: n= 1, so sum(1)=1.0 Example 2: Input: [2] Output: [1.5] Explanation: n sum(2)=1+1/2=1.5 O Iterative Approach: public static float sum iterative (int n) { } 1 0 Recursive Approach: Hint for recursive implementation: The prototype for the recursive approach should be as follows: Sum(n) = ( 1.0 if n== 1 Sum(n - 1) + 1/n if n >1 (2) public static float sum recursive (int n) { - = 2, soWrite a java program to find the distinct ways you can climb to the top (n steps to reach at the too) of stairs.

- Write a Java recursive method to print Fibonacci series of n terms. Fibonacci series starts with 0 and 1, and the sum of previous two numbers is the next number of the series. For instance, 0, 1, 1 (0 + 1), 2 (1 + 1), 3 (1 + 2), and so on.

Tip: Figure 5.17 in the textbook provides an example of a graph depicting performance improvements associated with loop unrolling. code: //normal code int main() { int n, sum=0; n=50; int a[50]; { for(int i=0; i<n; i++) { sum= sum +a[i]; } printf("sum is %d", sum); return 0; } //with unrolling int main() { int n, sum=0; n=50; int a[50] for(int i=0; i<n; i+=10) { scanf("%d", &a[i]); } sum= sum + a[0]; sum= sum + a[1]; sum= sum + a[2]; sum= sum + a[3]; sum= sum + a[4]; sum= sum + a[5]; sum= sum + a[6]; sum= sum + a[7]; sum= sum + a[8]; sum= sum + a[9]; printf("sum is %d", sum); return 0; }
- A graph G vertices represent switching centers and edges are communication lines between two centers.The bandwidth of a path in G is the bandwidth of its lowest bandwidth edge. The edges are marked by their bandwidth. Create java program, given a diagram and two switching centers a and b, will output the maximum bandwidth of a path between a and b. The program's inputs are n (switching centers number) ande (bandwidths/edges number). Following the e lines containing bandwidth information, which includes the switching centers and integer values of their respective bandwidths, the idea is to identify the two switching centers between which the maximum bandwidth is to be determined.Write a Java Program to take a number from the user and check whether that number is a power of 2?

The edges are marked by their bandwidth. Create java program, given a diagram and two switching centers a and b, will output the maximum bandwidth of a path between a and b. The program's inputs are n (switching centers number) ande (bandwidths/edges number), both are integers. Switching centers should characters value( A,B etc.) Following the e lines containing bandwidth information, which includes the switching centers and integer values of their respective bandwidths/weights, the idea is to identify the two switching centers between which the maximum bandwidth is to be determined. Program should first prompt user to enter n and e values, then source switching center to destination switching center with given weight/bandwidth (example A --> B 5, B --> C 1 etc)
