Assuming that 2-dimensional array data B[4][4] (each element is one word) is stored in memory. Assume cache block size is 16 bytes or 4 words. In other word, one block can have 4 consecutive array data. Assume the program is written in Fortran (Column-Major)Program X accesses B00, B01, B02, B03, B10, B11, ... B33 in this order. Program Y accesses B00, B10, B20, B30, B01, B11, ... B33 in this order. Considering only the accesses to array data B, what is the cache hit ratio of program X
