Question

java

random matches. Write a BinarySearch client that takes an int value T as
a command-line argument and runs T trials of the following experiment for N = 103, 104,
105, and 106: generate two arrays of N randomly generated positive six-digit int values,
and find the number of values that appear in both arrays. Print a table giving the average
value of this quantity over the T trials for each value of N.

Step 1: Introduction:

The experiment aims to study the number of overlaps between two randomly generated integer arrays for varying sizes. Specifically, for each array size , we generate two arrays of random six-digit integers and count the number of integers that appear in both arrays. By repeating this experiment times, we can derive an average number of overlaps for each array size .

Algorithm:

  1. Parse the command-line argument to get the value of .
  2. Initialize a list of array sizes .
  3. For each size in the list, execute the following steps:
    1. Initialize a variable to zero.
    2. Repeat times:
      1. Generate two random arrays of size .
      2. Sort the first array.
      3. For each element in the second array, perform a binary search on the sorted first array to check for its existence.
      4. Increment the totalMatches by the number of elements found.
    3. Compute the average number of overlaps for as Error converting from MathML to accessible text..
    4. Print the average number for .
