Webinitialize hash table so all slots marked as vacant for(i=0; i < n; i++) { insert A[i] into table at location hash(A[i]) (mark slot as occupied) } for(i=0,j=0; j < n; i++) { if table[i] is occupied { A[j] = item stored at table[i] j++ } } What is the complexity of this method? WebComplexity Analysis: The time complexity of inserting elements into the hash matrix is O (n), where n is the number of elements in the given array. The time complexity of searching for an element in the hash matrix is O (1) because we directly access the matrix using the index of the element.
