Answer:
import regex as re
def in_parentheses(a_string):
regeX = re.compile(".*?\((.*?)\)")
result = re.findall(regeX, a_string)
return str(result).replace("[","").replace("]","")
print("test 1: "+in_parentheses("Open ( only"))
print("test 2: "+in_parentheses("This is a sentence (words!)."))
Answer:
Elements
Explanation:
A computer code acts as a medium by which a person can communicate with the computer machine.
One such language is known as HTML or hypertext markup language. HTML stands for Hypertext markup language which is used to markup the language for web pages in computer.
The HTML series consists of a series of elements which are enclosed in the tags commonly called start tag and a stop tag.
Example <head>
here,
the head is a series of elements.
< start-tag
> stop-tag
Thus, element is the correct answer.
Answer:
In C++:
#include <bits/stdc++.h>
#include <iostream>
#include <vector>
using namespace std;
int main(){
vector<int> vectItems;
cout << "Vector length: ";
int ln; cin>>ln;
int num;
for (int ikk = 0; ikk < ln; ikk++){
cin >> num;
vectItems.push_back(num);}
int small, secsmall;
small = secsmall = INT_MAX;
for (int ikk = 0; ikk < ln; ikk++){
if(vectItems[ikk] < small){
secsmall = small;
small = vectItems[ikk]; }
else if (vectItems[ikk] < secsmall && vectItems[ikk] != small) {
secsmall = vectItems[ikk];} }
cout<<small<<" "<<secsmall;
return 0;}
