Consider the following method. public static int mystery(int[][] arr) \{ for (Int \( 1=0 ; 1<\operatorname{arr} \). length; \( 1++)\{ \) for (int \( j=0 ; j<\operatorname{arr}[0] .1 e n g t h ; j++)\{ \) if \( ((\operatorname{arr}[1][j] / 2) \% 2=0)\{ \) return arr[1][j]; return 0 ; What does return when the two-dimensional array \( \{\{2,3,4\},\{5,6,7\},\{8,9,10\}\} \) is passed as the parameter ? 5 3 2 6 4 Consider the following code segment, where letters is a two-dimensional (2D) array that contains possible letters. The code segment is intended to print "DOG" using column-major order. String [][] letters \( =\left\{\left\{{ }^{\prime \prime} D^{\prime \prime}\right.\right. \), "O", "G" \( \} \), \( \{ \) "O", "O", "-" \( \} \), \( \{ \) "G", "-", "G" \( \}\} \) System.out.println( \( /{ }^{*} \) missing code \( \left.* /\right) \); Which of the following could replace \( \quad \) so that the code segment works as intended? letters \( [1][1]+ \) letters \( [2][2]+ \) letters \( [3][3] \) letters \( [0][0]+ \) letters \( [1][1]+ \) letters \( [2][2] \) letters \( [0][0]+ \) letters \( [1][0]+ \) letters \( [2][0] \) letters \( [0][0]+ \) letters \( [0][1]+ \) letters \( [0][2] \) letters \( [1][1]+ \) letters \( [1][2]+ \) letters \( [1][3] \) Consider the following method, shift, which is intended to shift the elements of arr one to the left. For example, if arr contains \( \{\{1,2,3\},\{4,5,6\}\} \), then should return int[][] ret = new int[arr. length] [arr[0]. length]; for (int \( j=0 ; j<\operatorname{arr}[0] \). length \( -1 ; j++ \) ) \{ What choice could replace so that works as intended? \( \operatorname{ret}[i][0]=\operatorname{arr}[i][\operatorname{arr}[0] \cdot \) length \( -1] \) 1. \( \operatorname{ret}[i][\operatorname{arr}[0] \). length \( -1]=\operatorname{arr}[i][0] ; \) II. \( \operatorname{arr}[i][0]=\operatorname{ret}[i][\operatorname{arr}[0] \). length \( -1] ; \) II only I and III only I only I, II, and III III only Consider the following method. public int findElement(int[][] values) \{ int found = values \( [0][0] ; \) int result \( =0 \); for (int [] row : values) \{ for (int index \( =0 \); index < row. length \( \quad \) if (row[index] \( > \) found) \{ \( \quad \) found \( = \) row[index \( ] ; \) result \( = \) index; for (int index \( =0 \); index \( < \) row.length; index++) \{ Which of the following best describes what is returned by the method? The row index of an element with the smallest value in the two-dimensional array The row index of an element with the largest value in the two-dimensional array The smallest value in the two-dimensional array The column index of an element with the largest value in the two-dimensional array The largest value in the two-dimensional array
