Find a pda that accepts the language L = {a^(n)b^(2n) : n ≥ 0}

How does a link-based implementation of the List differ from an array-based implementation? Select one: a. All of these b. A link-based implementation does not need to shift entries over to make room when adding a new entry to the List c. A link-based implementation is sized dynamically so it takes up only the memory to hold the current entries d. A link-based implementation does not need to shift entries up to remove a gap when removing an entry from the List

C++ Implement the generic algorithm max_element(start, stop). Recall that this algorithm returns an iterator that points to the maximum element in the range [start,stop). If the range is empty, stop is returned. Elements are compared by using the < operator. The arguments start and stop are bidirectional iterators.

Write a Java program that: • Defines a linked list data structure to represent a collection of integers. • Populates the linked list with random integers. • Implements three different operations on the linked list: Finding the maximum element Finding the minimum element Calculating the sum of all elements • Tests these operations and ensures their correctness. Provide a big-Oh characterization, in terms of n, of the time complexity for each of the implemented operations on the linked list. Improve the linked list implementation to have a method for removing duplicates in O(N) time complexity.

Interpret this in plain english Φ = (a ⇒ b) ^ (c ⇒ b’) ^ (a’⊕ c)

1. Consider the following dynamic programming implementation of the Knapsack problem:   #include int find_max(int a, int b) {       if(a > b)          return a;       return b; } int knapsack(int W, int *wt, int *val,int n) {      int ans[n + 1][W + 1];      int itm,w;      for(itm = 0; itm <= n; itm++)          ans[itm][0] = 0;      for(w = 0;w <= W; w++)         ans[0][w] = 0;      for(itm = 1; itm <= n; itm++)      {           for(w = 1; w <= W; w++)           {                if(wt[itm - 1] <= w)                   ans[itm][w] = ______________;                else                   ans[itm][w] = ans[itm - 1][w];           }      }      return ans[n][W]; } int main() {      int w[] = {10,20,30}, v[] = {60, 100, 120}, W = 50;      int ans = knapsack(W, w, v, 3);      printf("%d",ans);      return 0; }   Which of the following lines completes the above code? A. find_max(ans[itm – 1][w – wt[itm – 1]] + val[itm – 1], ans[itm – 1][w]) B. find_max(ans[itm – 1][w –…

Give a CFG that generates {a^i b^j c^k d^l |i + k = j + l}. It suffices to give the rules.Your CFG should not be overly complicated.

Let G = ( { S,A,B,C,D}, {a,b,c}, P, S ), where P consists of the following productions.G: S  aSb | bSa | bAbA  aAa | cBB  CBD | D | C  a | bD  c | Convert G into its equivalent PDA which accepts L(G) by empty stack
