Answer:
A Red Black Tree is a type of self-balancing(BST) in this tree ,each node is red or black colored. The red black tree meets all the properties of the binary search tree, but some additional properties have been added to a Red Black Tree.
A Red-Black tree's height is O(Logn) where (n is the tree's amount of nodes).
In a red-black tree with black height k
The maximum number of internal nodes is 
.
The smallest possible number is 
.
Answer:
3% inflation rise. No correct cpi option
Explanation:
Consumer Price Index(CPI) is calculated by the Bureau of Economic Analysis and Statistics of a country monthly and annually.
Consumer Price Index(CPI) is used for measuring the changes in the price level of consumer goods and services purchased by households.
Calculating the consumer price index; price in 1964= $1.25, today price= $5.0.
Therefore, consumer price index= Price in today- price in 1964÷ price in 1964,.
Consumer Price index(CPI)= $(5-1.25)/1.25 = 3.75/1.25 = 3 Percent price inflation rise.
For the first cpi; 112-80/80= 0.4 percent( not equal to the 3 Percent inflation rise).
For the second cpi: 141.6-60/60= 1.36 Percent inflation rise(not equal to the 3 Percent inflation rise).
For the third CPI: 126.4-75/75 =0.68 percent inflation rise[not equal to the 3 Percent inflation rise].
For the third CPI: 108.5-90/90=0.21 percent inflation rise(not equal to 3 Percent inflation rise)
Therefore, none of the options are right.
Mobile phones transmit and receive signals using electromagnetic waves, that is, wireless signal are electromagnetic waves which can travel through a vacuum, they do not need a medium or matter.
<h3>What are electromagnetic waves?</h3>
They are generated by electrical and magnetic particles moving at the same time (oscillating).
<h3>Characteristics of electromagnetic waves</h3>
- Network waves are electromagnetic waves.
- A mobile phone has coverage when it receives electromagnetic waves from at least one base station.
- They do not necessarily require a material medium for their propagation.
Therefore, we can conclude that electromagnetic waves are those that do not need a material medium to propagate and include, among others, radio, television and telephone waves.

Since java.util.PriorityQueue doesn't use the Cloneable interface, I think it's safe to say that Serializable interfaces are implemented in all instances.
