write a function to check given string matches with given pattern





public class isMatchingWithWildcard {
public static void main(String [] args){

String str = "adsfabcxyzdefgh.do1docx";
if(isMatching(str, pattern))
System.out.print("Matching");
else

}
public static Boolean isMatching(String str, String pattern){
int l = pattern.length();
if(pattern.lastIndexOf("*") == l-1)
pattern= (String) pattern.subSequence(0, l-1);
if(pattern.charAt(0) == '*')
pattern= (String) pattern.subSequence(1, pattern.length());
pattern = pattern.replace("*", "__");
String [] patternArray = pattern.split("__");

Verify if the given password is valid or not


Verify if the given password is valid or not.
for a valid password it should follow these 2 condition
1. must be 5-12 characters long
2. must contain atleast one number and one lowercase & one upper character and a symbol



#include<stdio.h>
#include<string.h>
int main()
{
    char S[20],c;
    int i=0,l,L=0,U=0,N=0,Sy=0;
    gets(S);
    l=strlen(S);
    if(l>12 || l<5)
    {
        printf("\n\Invalid password \n");
        return 0;
    }
    while(S[i++]!=NULL)
        if(S[i-1]>='a'&&S[i-1]<='z')
            L=1;
        else if(S[i-1]>='A'&&S[i-1]<='Z')
            U=1;
        else if(S[i-1]>='0'&&S[i-1]<='9')

Kahan We Met



Geet is travelling to meet her boyfriend in Mumbai.
Aditya is travelling to Mumbai for his business meeting.
Geet starts from Delhi while Aditya starts from Bangalore. Both of them are travelling on bus passing from town to town.
They meet at a nondescript city and end up travelling together to Mumbai. By the end of the journey they fall in love and settle down.
Enough of Bollywood stories, The problem at hand is to find Kahan they met?

For all interested programmers, Represent this as a programming problem(Data Structure) and find the location where Geet and Aditya would have met.

P.S. No need to actually find any city on the map where they met.
