a) Write a program to generate N-pairs (ui, vi), 1 ≤ i ≤ N uniformly distributed in the range [0, 1).
Plot these N pairs on a unit square where the ith point has coordinates (ui, vi), 1 ≤ i ≤ N and N= 103.
b) Using the Monte Carlo method, estimate the value of /4 using N pairs of
samples: N= 103, 104, 105, 106. Plot the estimates vs N.
