Consider the following two C code segments. Y and X are one and two dimensional arrays of size n and n x 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: for (i = 0; i < n; i++) Y[i] += X[0][i]; Code segment 2: 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 segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
