Chapter 20.6, Problem 20.6.7CP
Write a statement that sorts a two-dimensional array of double[] [] in increasing order of their second column. For example, if the array is double[] [] x = {{3, 1), {2, −1}, {2, 0}}, the sorted array will be {{2, −1), {2, 0), {3, 1}}.

An array is special if every even index contains an
even number and every odd index contains an odd number.
Create a function that returns true if an array is
special, and false otherwise.
Examples
isSpecialArray([2,
7, 4, 9, 6, 1, 6, 3]) → true
// Even indices: [2, 4, 6, 6]; Odd indices: [7, 9, 1,
3]
isSpecialArray([2, 7, 9, 1, 6, 1, 6, 3]) → false
// Index 2 has an odd number 9.
isSpecialArray ([2, 7, 8, 8, 6, 1, 6, 3]) → false
// Index 3 has an even number 8.
Java Programming :
A party has been organised on cruise. The party is organised for a limited time (T).
The number of guests entering (E[i]) and leaving (L[i]) the party at every hour is represented as elements of the array.
The task is to find the maximum number of guests present on the cruise at any given instance within T hours.
Example 1:
Input :
5 > Value of T
[7,0,5,1,3] -> E[], Element of E[0] to E[N-1], where input each element is separated by new line
[1,2,1,3,4] -> L[], Element of L[0] to L[N-1], while input each element is separate by new line.
Output :
8
-> Maximum number of guests on cruise at an instance.
Explanation:
1st hour:
Entry 7 Exit: 1
No. of guests on ship : 6
2nd hour :
Entry Exit : 2
No. of guests on ship: 6-2=4
Hour 3:
Entry: 5 Exit: 1
No. of guests on ship : 4+5-1-8
Hour 4:
Entry 1 Exit 3
No. of guests on ship: 8+1-3=6
Hour 5:
Entry 3 Exit: 4
No. of guests on ship: 6+3-4-5
Hence, the maximum number of guests within 5 hours is 8.
Q2. By applying the concept of array in C language, solve the equation as shown in Figure Q2
below where the values of n is the last digit of student matrix number (e.g. CD12345), and
u is the second digit of student matrix number (e.g. CD12345). User need to insert the value
in array x[i] series, for example, EE x; = x [0] + x[1]+ x[2],where xri is a series of value
in data set.
