You are encouraged to solve this task according to the task description, using any language you may know.
Given two strings, demonstrate the following 3 types of matchings:
- Determining if the first string starts with second string
- Determining if the first string contains the second string at any location
- Determining if the first string ends with the second string
Optional requirements: A) Print the location of the match for part 2 B) Handle multiple occurrences of a string for part 2.
C++
<lang cpp>
- include <string>
using namespace std;
string s1="abcd"; string s2="abab"; string s3="ab"; //Beginning s1.compare(0,s3.size(),s3)!=0; //End s1.compare(s1.size()-s3.size(),s3.size(),s3)!=0; //Anywhere s1.find(s2)//returns string::npos int loc=s2.find(s3)//returns 0 loc=s2.find(s3,loc+1)//returns 2 </lang>
Python
<lang python> "abcd".startswith("ab")#returns true "abcd".endswith("zn")#returns false loc="abab".find("bb")#returns -1 loc="abab".find("ab")#returns 0 loc="abab".find("ab",loc+1)#returns 2 </lang>
