Which of these keywords must be used to handle the exception thrown by try block in some rational manner? What is the process of transforming raw data into a structured format suitable for analysis called? In Java, can a "catch" block catch exceptions of a superclass type? What will be the output of the following C++ code? #include <iostream> #include <string> using namespace std; class Mammal { public: virtual void Define(){ cout<<"I'm a Mammal\n"; } }; class Human: public Mammal { public: void Define(){ cout<<"I'm a Human\n"; } }; class Male: public Human { public: void Define(){ cout<<"I'm a Male\n"; } }; class Female: public Human { public: void Define(){ cout<<"I'm a Female\n"; } }; int main(int argc, char const *argv[]) { Mammal *M = new Mammal(); Male m; Female f; *M = m; M->Define(); M = &m; M->Define(); return 0; } What is the time complexity of the following dynamic programming implementation of the matrix chain problem? #include<stdio.h> #include<limits.h> int mat_chain_multiplication(int *mat, int n) { int arr[n][n]; int i,k,row,col,len; for(i=1;i<n;i++) arr[i][i] = 0; for(len = 2; len < n; len++) { for(row = 1; row <= n - len + 1; row++) { col = row + len - 1; arr[row][col] = INT_MAX; for(k = row; k <= col - 1; k++) { int tmp = arr[row][k] + arr[k + 1][col] + mat[row - 1] * mat[k] * mat[col]; if(tmp < arr[row][col]) arr[row][col] = tmp; } } } return arr[1][n - 1]; } int main() { int mat[6] = {20,5,30,10,40}; int ans = mat_chain_multiplication(mat,5); printf("%d",ans); return 0; }
