Question

Implement the following function, without using any data structure or #include <bits/stdc++.h>

/* Given two vectors of chars, check if the two vectors are permutations of each other, i.e., they contains same values, in same or different order.
e.g., V1=[‘a’,’b’,’a’] and V2=[‘b’,’a’,’a’] stores same multi-set of data points: i.e., both contains two ‘a’, and one ‘b’.

e.g., V3=[‘a’,’c’,’t’,’a’] and V4=[‘a’,’c’,’t’] are not same multi-set. V3 contains two ‘a’s, while V4 has only one ‘a’.

Note: when considering multiset, the number of occurrences matters. @param list1, list2: two vectors of chars

@pre: list1, list2 have been initialized

@post: return true if list1 and list2 stores same values (in same or different order); return false, if not. */



bool SameMultiSet (vector<char> list1, vector<char> list2)

 

 

THIS IS NOT THE CORRECT SOLUTION

/ include headers

#include <bits/stdc++.h>

// deinfe the namespace

using namespace std;

// function fo rchecking same

bool checkSame(vector<int> arr,vector<int> arr1)

{

// define a flag variables

int flag=0;

// loop from 0 to size of arr

for(int i=0;i<arr.size();i++)

{

// initialize flag=0

flag=0;

// loop from 0 to size of arr1

for(int j=0;j<arr1.size();j++)

{

// if arr[i] is equal to arr[j]

if(arr[i]==arr1[j])

{

  

// make flag as 1

flag=1;

// remove arr1[j] from arr1

vector<int>::iterator it;

it = arr1.begin()+j;

arr1.erase(it);

// break and move to next element

break;

}

}

// if flag is still 0

// return 0

if(flag==0)

{

return 0;

}

}

// return 1 after comparing

return 1;

}

 

// main function for testing

int main()

{

// call function and print answer accordinly

checkSame({1,2,3,4,5},{5,4,3,2,1})?cout<<The vectors are same:cout<<The vectors are not same;

 

return 0;

}
