Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame.Code segment 1: //initialize elements of y to 0 //initialize elements X[i] [j] of X to i+j for (i = 0; i < n; i++) Y[i] += X[0] [i];Code Segment 2: //initialize elements of Y to 0 //initialize elements X[i] [j] of X to i+j for (i = 0; i < n; i++) Y[i] += X[i] [0];Which of the following statements is/are correct?S1: Final contents of array Y will be same in both code segmentsS2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memoryS3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory |
