What do programming skills entail?

Programming, or "coding," skills are the ability to write commands in a variety of programming languages to tell a computer, application, or software program what to do and how to do it.

Write program for the distance travelled by ball.

height = float(input('Enter the height from which the ball is dropped: '))

bounci_index = float(input('Enter the bounciness index of the ball: '))

bounces = int(input('Enter the number of times the ball is allowed to

continue bouncing: '))

distance = height

for i in range(bounces-1):

height *= bounci_index

distance += 2*height

distance += height*bounci_index

SQL is considered difficult to learn; its command set has a vocabulary of more than 300 words.
a. True
b. False

Answers

Answer:

Explanation:

a. True

SQL (Structured Query Language) is a programming language used to manage data in relational databases. While it is relatively easy to learn the basic concepts of SQL, it can become more challenging as you learn the more advanced concepts and try to write more complex queries.

The command set for SQL does have a relatively large vocabulary, with over 300 words and commands that can be used to perform various tasks such as creating and modifying tables, inserting, updating and retrieving data from a database. It also can have slight variations depending on the specific implementation of SQL such as ANSI SQL, MySQL SQL, PostgreSQL SQL.

It's not necessarily difficult to learn, but it does take time and practice to become proficient in it. There are many resources available online that can help you learn SQL, such as tutorials, videos, and documentation, and many SQL tutorials are available for free. You can also practice by creating your own small databases and experimenting with different queries.

Problem Statement We have a two-dimensional board game involving snakes. The board has two types of squares on it: +'s represent impassable squares where snakes cannot go, and 0's represent squares through which snakes can move. Snakes may move in any of four directions - up, down, left, or right - one square at a time, but they will never return to a square that they've already visited. If a snake enters the board on an edge square, we want to catch it at a different exit square on the board's edge. The snake is familiar with the board and will take the route to the nearest reachable exit, in terms of the number of squares it has to move through to get there. Write a function that takes a rectangular board with only +'s and 0 's, along with a starting point on the edge of the board (given row first, then column), and returns the coordinates of the nearest exit to which it can travel. If multiple exits are equally close, give the one with the lowest numerical value for the row. If there is still a tie, give the one of those with the lowest numerical value for the column. If there is no answer, output
−1−1
The board will be non-empty and rectangular. All values in the board will be either
+
or 0 . All coordinates (input and output) are zero-based. All start positions will be 0 , and be on the edge of the board. For example,
(0,0)
would be the top left corner of any size input. Example Input Consider the following board: If a snake starts at the edge on the left (row 2 column 0 ), the snake will take the following path to another edge square (an exit) If the snake starts where the last one ended (row 5 column 2), the snake has two paths of length 5:
