In order to reach the top of a pole, a monkey in his first attempt reaches to a height of 5 feet and in the subsequent jumps, he slips down by 2% of the height attained in the previous jump. The process repeats and finally the monkey reaches the top of the pole. Write a program to input height of the pole. Calculate and display the number of attempts the monkey makes to reach the top of the pole.
Answer
import java.util.Scanner;
public class KboatMonkeyPole
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter height of the pole: ");
double poleHt = in.nextDouble();
double jumpHt = 5.0;
int numAttempts = 1;
while (jumpHt < poleHt) {
jumpHt += 5.0;
jumpHt -= 2 * jumpHt / 100.0;
numAttempts++;
}
System.out.println("Number of Attempts = " + numAttempts);
}
