What does the 'strcat' function in C do? What is the output of the following code? #include<stdio.h> #include<string.h> int get_min(int a, int b) { if(a < b) return a; return b; } int edit_distance(char *s1, char *s2) { int len1,len2,i,j,min; len1 = strlen(s1); len2 = strlen(s2); int arr[len1 + 1][len2 + 1]; for(i = 0;i <= len1; i++) arr[i][0] = i; for(i = 0; i <= len2; i++) arr[0][i] = i; for(i = 1; i <= len1; i++) { for(j = 1; j <= len2; j++) { min = get_min(arr[i-1][j],arr[i][j-1]) + 1; if(s1[i - 1] == s2[j - 1]) { if(arr[i-1][j-1] < min) min = arr[i-1][j-1]; } else { if(arr[i-1][j-1] + 1 < min) min = arr[i-1][j-1] + 1; } arr[i][j] = min; } } return arr[len1][len2]; } int main() { char s1[] = "abcd", s2[] = "defg"; int ans = edit_distance(s1, s2); printf("%d",ans); return 0; } Which NLP task involves identifying and analyzing the meaning and relationships between words in a sentence or document? What should be expression1 evaluate to in using ternary operator as in this line? expression1 ? expression2 : expression3 What will be the output of the following Java program? class equality { int x; int y; boolean isequal() { return(x == y); } } class Output { public static void main(String args[]) { equality obj = new equality(); obj.x = 5; obj.y = 5; System.out.println(obj.isequal()); } }
