Answer:
00(01)*+|(01)*+101|00(01)*+101
Rest detail is in explanation.
Explanation:
(01)* means all the strings comprising of 0 and 1
when we add + the set includes empty sets as well. and for or we use union, and this can be done using the | sign.
And for concatenation, we have like 00(01)* etc. Hence, the above regular expression.
Answer:
see explaination
Explanation:
The following code is in python 3.5 and above:
# Create a main method
def main():
# Accept name from the user
name = input("Enter your name: ")
# Accept describe yourself from the user.
describe = input("Describe yourself: ")
# Create a file object
f = open('person.html','w')
# Creat a string to store the html script.
message = """<html>
<head>
</head>
<body>
<center>
<h1>"""+name+"""</h1>
</center>
<hr/>"""+describe+"""<hr/>
</body>
</html>"""
f.write(message)
f.close()
main()
Answer:
#include <iostream>
#include <map>
using namespace std;
int main()
{
map<int, int> numbers;
cout << "Enter numbers, 0 to finish" << endl;
int number;
while (true) {
cin >> number;
if (number == 0) break;
numbers[number]++;
}
for (pair<int, int> element : numbers) {
std::cout << element.first << ": occurs " << element.second << " times" << std::endl;
}
}
Explanation:
One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.
They are arranged the way they are because of the QWERTY layout. It was used to slow down how people typed so they wouldn't get the typewriter jammed. Hope this helps. :)
