List slicing: • Slicing is a concept of selecting a range of elements from a list. • In Python, an expression that selects a subsection of a list is known as a slice. • A slice is a span of elements that are taken from a list. • Normally, the slice expression has a start index and an end index for slicing. • In case if the start and end indices are not provided, the python employs 0 as the start index and length of the list as the end index. Syntax: In Python, the list slice statement without the start index and end index can be expressed as follows: listname[:] Explanation: In the list slice syntax, • As the “start” index is not provided, python uses 0 as the start index by default. • As the “end” index is not provided, Python employs the length of the list as the “end” index for the slice. • The list slice expression returns a copy of the entire list.

Program Plan Intro

List slicing:

• Slicing is a concept of selecting a range of elements from a list.

• In Python, an expression that selects a subsection of a list is known as a slice.

• A slice is a span of elements that are taken from a list.

• Normally, the slice expression has a start index and an end index for slicing.

• In case if the start and end indices are not provided, the python employs 0 as the start index and length of the list as the end index.

Syntax:

In Python, the list slice statement without the start index and end index can be expressed as follows:

listname[:]

Explanation:

In the list slice syntax,

• As the “start” index is not provided, python uses 0 as the start index by default.

• As the “end” index is not provided, Python employs the length of the list as the “end” index for the slice.

• The list slice expression returns a copy of the entire list.

Write a Java Program to manage student information of a university. The Javaprogram does the following steps:a) The program must use single-dimensional arrays to store the studentinformation such as Student ID, Name and Major.b) The program asks the user to provide the number of students.c) The program asks the user to enter the Student IDs for the number of studentsand stores them.d) The program asks the user to enter the corresponding names for the numberof students and stores them.e) The program then asks the user to provide the corresponding major for thestudents and stores them.f) The program then should display the following options:1. ID Search2. Major Enrollment3. Exitg) On selecting option 1, the user can search for a student using Student ID. Theprogram asks the user to enter a Student ID. It then should print thecorresponding student’s details such as Name and Major if the user providedStudent ID number is present in the stored data. If the user’s Student IDnumber does not…

(a) Algebraically determine the output state |q3q2q1q0> (which is a 4-qubitvector in 16-dimensional Hilbert space). Show all steps of your calculations. (b) Run a Qiskit code which implements the circuit and append threemeasurement gates to measure the (partial) output state |q2q1q0> (which is a 3-qubit vector in 8-dimensional Hilbert space). this is for quantum soft dev class, you can use stuff like Deutsch Jozsa if u want

Write a C++ program that will count from 1 to 10 by 1. The default output should be 1, 2, 3, 4, 5, 6 , 7, 8, 9, 10 There should be only a newline after the last number. Each number except the last should be followed by a comma and a space. To make your program more functional, you should parse command line arguments and change behavior based on their values. Argument Parameter Action -f, --first yes, an integer Change place you start counting -l, --last yes, an integer Change place you end counting -s, --skip optional, an integer, 1 if not specified Change the amount you add to the counter each iteration -h, --help none Print a help message including these instructions. -j, --joke none Tell a number based joke. So, if your program is called counter counter -f 10 --last 4 --skip 2 should produce 10, 8, 6, 4 Please use the last supplied argument. If your code is called counter, counter -f 4 -f 5 -f 6 should count from 6. You should count from first to last inclusively.…
