https://drive.google.com/file/d/1cBMx_IECHS2f6FvA433w6sb2NlC4-Bah/view?usp=sharingWrite program that applies concept of varags method to create function, display() which takes 3 parameters: (1) one parameter named object of String type, (2) one array called atoms, of String type, and (3)variable-length list of parameters named n. Import Scanner class to source file. In the main() function, use tools provided by the Scanner class to take three string literals as inputs one by one. • The first input is the name of a subject (ex: “glucose”). • The 2nd input is list of atomic symbols (ex: C Cl Na O) • The 3rd input is list of integers (ex: 18 12 5 2). Then, call display() function and pass the 3 inputs as values of parameters of display() function. Upon receiving the values, the display() function must be able to split string literals properly into arrays of String type, except the one passed to object parameter. Ex:
Enter the name of a subject: glucose
Enter list of atomic symbols: C H O
Enter list of integers: 6 12 6
The molecular formula of glucose is C6H12O6
Create one array “sign” of char type whose elements are 'H', 'D', 'S', and 'C'. Create one variable “n” of int type whose initial value is -1 and other variable named “i” of int type whose initial value is also -1. Create function named “pickCard()” of void type that randomly generate two integers. Limit first random number with range of 0 to 3,then assign randomly generated number to “i” variable. Limit second random number with range from 1 to 13, then assign the randomly generated number to “n” variable. Then, make sure “pickCard()” function can display one of “sign” array's values according to value assigned to “i” variable. Have “pickCard()” function display the value assigned to the “i” variable and meet all conditions specified in the following table
Value of i | Display
1 | A
11 | J
12 | Q
13 | K
Finally, use a while loop to call the “pickCard()” 5 times.

Sum of Prime Numbers In the Input
Given a list of integers, write a program to print the sum of all prime numbers in the list of integers.
Note: One is neither prime nor composite number.Input
The input will be a single line containing space-separated integers..Output
The output should be a single line containing the sum of all prime numbers from 1 to N.Explanation
For example, if the given list of integers are
2 4 5 6 7 3 8As 2, 3, 5 and 7 are prime numbers, your code should print the sum of these numbers. So the output should be 17.

Mean, Median and Mode
Given a list of integers, write a program to print the mean, median and mode.
Mean - The average value of all the numbers.
Median - The mid point value in the sorted list.
Mode - The most common value in the list. If multiple elements with same frequency are present, print all the values with same frequency in increasing order.Input
The input will be a single line containing space-separated integers.Output
For example, if the given list of integers are
2 6 3 1 8 12 2 9 10 3 4The average of all the numbers is 5.45
After sorting the array,
1 2 2 3 3 4 6 8 9 10 12as the length of the list is an odd number, the median will be the middle number in the sorted list. So the median will be 4.
As 2 and 3 are having the same frequency, the mode will be 2 3.
So the output should be
Mean: 5.45
Median: 4
Mode: 2 3Sample Input 1
2 4 5 6 7 8 2 4 5 2 3 8
Sample Output 1
Mean: 4.67
Median: 4.5
Mode: 2
Sample Input 2
2 6 3 1 8 12 2 9 10 3 4
Sample Output 2
Mean: 5.45
Median: 4
Mode: 2 3
Shift Numbers - 2
Given a string, write a program to move all the numbers in it to its start.Input
The input will contain a string A.Output
The output should contain a string after moving all the numbers in it to its start.Explanation
For example, if the given string A is "1good23morning456", the output should be "123456goodmorning", as it contains numbers at the start.
Sample Input 1
1good23morning456
Sample Output 1
123456goodmorning

Sum of Prime Numbers from M to N
Given two integers M and N, write a program to print the sum of prime numbers from M to N. (Both M and N are inclusive).Input
The first line of input will contain a positive integer (M).
The second line of input will contain a positive integer (N).Output
The output should be a single line containing the sum of prime numbers from M to N.Explanation
For example, if the given M and N are 5 and 11, as all the prime numbers from 5 to 11 are 5, 7, and 11. So the output should be sum of these primes (5+7+11), which is 23.
Similarly, if the given numbers are M is 18 and N is 40, as all the prime numbers from 18 to 40 are 19, 23, 29, 31,and 37. So the output should be sum of these primes (19+23+29+31+37), which is 139.
