Question

Assume x contains at least one row and at least one column and jis a valid index in x. In plain English, what is being returned by the Java method below when it is called? int i) { 0; public static int f(int[][] x, int p = 0; int i do { p+= x[j][i]; i++; } while(i < x[j].length); return p; } the sum of the values in the column at index i in x the sum of the values in the row at index j in x the sum of the values in the column at index j in x a reference to p the sum of the values in the row at index i inx

Answer 1

public static int f(int [][] x,int j)
{
int p=0;
int i=0;
do {
// Adding the value of element of x for row_index=j and col_index=i
// j is constrant means row_index value constant and i incremented
// till the length of the row. Means p stores the sum of all the
// element of row index j.
p+=x[j][i];
i++;
}while(i<x[j].length);
return p;
}
  

Answer:- The sum of the values in the row at index j in x. (Option 2)
