Let $A = \{ a_1, . . . , a_n \}$ and $B = \{b_1, . . . , b_m\}$ be two sets of numbers. Consider the problem of finding their in

Digiron [165]

<h2>Answer: Pseudo code</h2>

Initialize intersection I as empty.

Find smaller of m and n and sort the smaller array.

function printIntersection(int arr1[ ], int arr2[ ], int m, int n)

{

// Before finding intersection, make sure arr1[0..m-1]

// is smaller

if (m > n)

{

int *tempp = arr1;

arr1 = arr2;

arr2 = tempp;

int temp = m;

m = n;

n = temp;

}

// Now arr1[ ] is smaller

// Sort smaller array arr1[0..m-1]

sort(arr1, arr1 + m);

// Search every element of bigger array in smaller

// array and print the element if found

for (int i=0; i<n; i++)

if (binarySearch(arr1, 0, m-1, arr2[i]) != -1)

cout << arr2[i] << " ";

}

3) For every element x of larger array, do following

…….b) Binary Search x in smaller array. If x is present, then copy it to I.

int binarySearch(int arr[], int l, int r, int x)

{

if (r >= l)

{

int mid = l + (r - l)/2;

// If the element is present at the middle itself

if (arr[mid] == x) return mid;

// If element is smaller than mid, then it can only

// be presen in left subarray

if (arr[mid] > x)

return binarySearch(arr, l, mid-1, x);

// Else the element can only be present in right subarray

return binarySearch(arr, mid+1, r, x);

}

// We reach here when element is not present in array

return -1;

}

4) Return I.

Explanation:

Time complexity of this method is min(mLogm + nLogm, mLogn + nLogn) which can also be written as O((m+n)Logm, (m+n)Logn). This approach works better than the different approaches like hashing when difference between sizes of two arrays is significant.

Vedmedyk [2.9K]

Compared with other countries, doing business with Vietnamese people is comes in mixed traditional and modern type. Those who would like to do business in Vietnam should study how they do good business with them.

Based on the experiences written on Principles of Business, business cards <span>should be given at the same time</span>. It is considered a polite action when the business card presented to them is written in both languages. The Vietnamese language should be facing up. <span>Exotic food is served during the meal while small drinks should be taken. They do not want conversations to be in a fast-phase. Talk in a low voice.</span>
