Program Plan Intro

A method “toString()”

Program plan:

  • Define the method “toString()”,
    • Return the value obtained from the method “toString()”.
  • Define the overloaded method “toString()”,
    • Check whether the root is  null,
      • If it is true, return the sting “empty”.
        • Check whether the left and right child of the root is null,
          • If it is true, return the value in the node.
        • Otherwise, return the value obtained from the expression that includes function call to the parameterized method “toString()” for left and right child of the root.

Can you help me solve this problem using Master's Theorem:Solve the recurrence relation f(n) = 3af(n/a) + (n + a)2 with f(1) = 1 and a > 1 byfinding an expression for f(n) in big-Oh notation.
here is example 7.6## Example 7.6 Suppose the sample population is χ 2 (2), which is non-normal but with same variance 4. ▶ Repeat the simulation, but replacing the N(0, 4) samples with χ 2 (2) samples. ▶ Calculate the empirical confidence level.(Empirical confidence level) n <- 20 alpha <- 0.05 UCL <- replicate(1000, expr = { x <- rchisq(n,df=2) (n-1)*var(x)/qchisq(alpha,df=n-1) }) sum(UCL >4) mean(UCL > 4) ## t.test function n <- 20 x <- rnorm(n,mean=2) result <- t.test(x,mu=1) result$statistic result$parameter result$p.value result$conf.int result$estimate
