#include<iostream>
using namespace std;

bool isMember(char arr[],int n,char ch)
{
    if(arr[n]==ch)              //base condition.
        return true;
    if(arr[n]!=ch&&n<=0) //base condition
            return false;

    return isMember(arr,n-1,ch);

}
int main()
{
        char arr[]={'a','b','c','d'};
        int n=4;
        char ch1='a';
        char ch2='e';

        if(isMember(arr,n-1,ch1))
          cout<<"value:"<<ch1<< " founded\n";
        else
          cout<<"value:"<<ch1<<" NOT found\n";


        if(isMember(arr,n-1,ch2))
          cout<<"value:"<<ch2<< " founded!!!!\n";
        else
          cout<<"value:"<<ch2<<" NOT found\n";
}

2 Write a function named equivalentArrays that has two array arguments and returns 1 if the two arrays contain the same values (but not necessarily in the same order), otherwise it returns 0. Your solution must not sort either array or a copy of either array! Also you must not modify either array, i.e., the values in the arrays upon return from the function must be the same as when the function was called. Note that the arrays do not...
