Stream of Characters in C++
Suppose we want to implement the StreamChecker class as follows −StreamChecker(words) − This is the constructor, this initializes the data structure with the given words.query(letter) − This returns true when for some k >= 1, the last k characters queried (in order from oldest to newest, including this letter just queried) spell one of the words in the given list.So, if the input is like word list = ["ce", "g", "lm"], then call query many times for [a, b, c, e, f, g, h, i, j, k, l, m], then the output will be true for e, g, m, and ...
Read MoreHow to remove the tick marks in JavaFX XY charts?
The javafx.scene.XYChart class is the base class of all the charts that are plotted in an x-y pane. By instantiating the subclasses of this class you can create various XY charts namely − line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc.In the XY chart, the given data points are plotted on an XY plane. Along the x and y axes, you will have the tick marks and tick labels. The tick marks represent various values with uniform intervals.Removing the tick marksThe javafx.scene.chart.Axis class (abstract) is the base class of all the axes in XY charts. ...

Read MoreHow to create a bubble chart with two parameters in JavaFX?
The bubble chart accepts a series of data points (x, y) as input values and, creates bubbles for the data points in the given series. In JavaFX, you can create a bubble chart by instantiating the javafx.scene.chart.BubbleChart class.Generally, in all X-Y charts, the data points plot two values (x, y). In the bubble chart, there is a third value which is represented by the radius of the bubble. This chart comes handy while plotting the data points in 3 dimensions.Anyhow, it is not mandatory to have the third value, it is only optional. Like any other XY chart, you can ...

Inline chart, the data values have represented a series of points connected by a line. In JavaFX, you can create a line chart by instantiating the javafx.scene.chart.LineChart class.By default, A JavaFX Line chart contains symbols pointing out the values in the series along the x-axis. Typically, these are small circles.The X-Axis on the bottom in the plot.Y-Axis on the left.Moving the X-Axis to topThe Axis class (superclass of all axes) has a property named side, this specifies the side of the plot at which you need to have the current axis (left, right, top-bottom). You can set the value to ...

Read MoreHow to set the slices of a JavaFX PieChart in anti-clockwise direction?
The pie chart is a data a circular statistical graphic, where the data values are represented as the slices of a circle. Each slice is differentiated from other (typically by color). In JavaFX, you can create a pie chart by instantiating the javafx.scene.chart.PieChart class.Changing the direction of the slicesThe angle at which the first slice of a PieChart is started is known as start angle and you can set this value using the setStartAngle() method (by default, 0).The PieChart class provides a property (boolean) known as clockWise specifying whether the slices of the current PieChart are in a clockwise direction ...
Read MoreHow to change the position of the legend in a PieChart in JavaFX?
In the pie chart, we represent the data values as slices of a circle. Each slice is differentiated from other (typically by color). In JavaFX, you can create a pie chart by instantiating the javafx.scene.chart.PieChart class.By default, a JavaFX pie chart contains labels of the slices and a legend − a bar with colors specifying the category represented by each color.Changing the position of the Legend −The PieChart class has a property named legendSide (inherited from the Chart class). This specifies the position of the legend in the chart (left, right, top-bottom). You can set the value to this property ...

A menu is a list of options or commands presented to the user, typically menus contain items that perform some action. The contents of a menu are known as menu items and a menu bar holds multiple menus.A button controls in user interface applications, in general, on clicking the button it performs the respective action.A SplitMenuButton provides the functionality of both buttons and a Menu. It is divided into two areas − action area and, menu area.
