One image is the question the other is an example

Please type your solution so that I will be able to read them

If it's too long just work on what you can do and then I'll ask the question again to get the rest if needed 

3. Virtual memory Study the two functions given below. Both use the same array declared as: static int data[256*256*8]; void function1() { int i; int j; for (i = 0; i < 32; i++) for (j = 0; j< 256; j++) data[i] = i; } void function2() { int i; int j; for (i = 0; i < 32; i++) for (j = 0; j< 256; j++) data[j*2048] = i; }

Assume the following behaviors in a virtual memory system. Reading or writing physical memory requires 50 nanoseconds. Reading or writing disk writing 10 milliseconds. Page size is 8 kilobytes. Presume that the program has 1 megabyte of physical memory available. You may consider everything except the array access itself to take no time. You should also assume that the first 1 megabyte of the array is in physical memory initially. You may ignore any memory used by the program or stack to execute these functions. Using this information, answer the following questions. In each case, show the work you use to calculate the answer. Give your answer in a reasonable unit. d) Just considering virtual memory access time, how long will it take for function1() to execute?
