Chapter 7, Problem 25C
Program Plan Intro

Program Plan:

1. Below mentioned variables are used:

  • ArrayList-integer array List
  • size- capacity of array List.
  • front- Index 0 of array.
  • rear-end of array.

2. Below Mentioned functions are used:

  • enQueue()-toinsert the element in a circular array list
  • deQueue()-to delete the rear element.
  • displayQ()-display the elements of queue.
  • main()-main function in program that reads the input from user anddisplays the output.

Program description:

This program is for creating a circular array list which has a constant capacity. Since this is a circular array the front and rear positions are the same. So insertion of an element or deletion if an element need not requires a loop.

using r language for integration theta = integral 0 to infinity (x^4)*e^(-x^2)/2 dx (1) use the density function of standard normal distribution N(0,1) f(x) = 1/sqrt(2pi) * e^(-x^2)/2 -infinity <x<infinity as importance function and obtain an estimate theta 1 for theta set m=100 for the estimate whatt is the estimate theta 1? (2)use the density function of gamma (r=5 λ=1/2)distribution f(x)=λ^r/Γ(r) x^(r-1)e^(-λx) x>=0 as importance function and obtain an estimate theta 2 for theta set m=1000 fir the estimate what is the estimate theta2? (3) use simulation (repeat 1000 times) to estimate the variance of the estimates theta1 and theta 2 which one has smaller variance?
