Computer Virtual Lans Difficulty: Medium

. . . . . . . . abstract class has three main methods for loading data and for most use cases it would suffice to extend it. Which of these methods of class String is used to check whether a given object starts with a particular string literal? What is the value stored in arr[2][3] when the following code is executed? #include<stdio.h> #include<string.h> int max_num(int a, int b) { if(a > b) return a; return b; } int lcs(char *str1, char *str2) { int i,j,len1,len2; len1 = strlen(str1); len2 = strlen(str2); int arr[len1 + 1][len2 + 1]; for(i = 0; i <= len1; i++) arr[i][0] = 0; for(i = 0; i <= len2; i++) arr[0][i] = 0; for(i = 1; i <= len1; i++) { for(j = 1; j <= len2; j++) { if(str1[i-1] == str2[j - 1]) arr[i][j] = 1 + arr[i - 1][j - 1]; else arr[i][j] = max_num(arr[i - 1][j], arr[i][j - 1]); } } return arr[len1][len2]; } int main() { char str1[] = "hbcfgmnapq", str2[] = "cbhgrsfnmq"; int ans = lcs(str1,str2); printf("%d",ans); return 0; } How can you create an infinite generator in Python? What is the correct function prototype of () operator overloading?
