Program 1, Histogram, takes an integer n, and two integers left and right, and uses StdDraw to plot a histogram of the count of the numbers in the standard input stream that fall in each of the n intervals defined by dividing (left, right) into n equal-sized intervals.

Note: The program is to read the values from an input file whose first line would contain n, left, and right values. The remaining lines would contain the sequence of integer values.

A sample run would be as follows.

It should plot a histogram where the x-axis points are 40, 50, 60, 70, 80 and the intervals are 40-50, 50-60, 60-70, 70-80. The height of the rectangles for the intervals should be 3, 4, 7, 6 respectively.
