Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.</span>
Roman numerals are V for 5, X for 10, L for 50, C for 100, D for 500, and M for 1,000.
Recall that some numbers are formed by using a kind of subtraction of one Roman “digit”; for example, IV is 4 produced as V minus I, XL is 40, CM is 900, and so on.
A few sample years: MCM is 1900, MCML is 1950, MCMLX is 1960, MCMXL is 1940, MCMLXXXIX is 1989.
(Hints: Use division and mod.)
Assume the year is between 1000 and 3000.
Answer:
def remove_duplicates(lst):
no_duplicate = []
dup = []
for x in lst:
if x not in no_duplicate:
no_duplicate.append(x)
else:
dup.append(x)
for y in dup:
if y in no_duplicate:
no_duplicate.remove(y)
return no_duplicate
Explanation:
Create a function called remove_duplicates that takes one parameter, lst
Create two lists one for no duplicate elements and one for duplicate elements
Create for loop that iterates through the lst. If an element is reached for first time, put it to the no_duplicate. If it is reached more than once, put it to the dup.
When the first loop is done, create another for loop that iterates through the dup. If one element in no_duplicate is in the dup, that means it is a duplicate, remove that element from the no_duplicate.
When the second loop is done, return the no_duplicate
Answer: Following are the sequence-wise answers to blanks :
1)programmer
2)problems
3)user
4)algorithm
5)programming language
6)program
7)computer
Explanation:
To solve any situation, firstly an algorithm is designed which can be in English as well and its optimized and a language is chosen according to the system's configuration and many factors and then that algorithm is converted to code in same language chosen. This is how a user's situation is solved using programming by a coder or programmer.
Microcomputers are currently the most popular.
