1. Assume an array contains 20 words of data with an index that starts with a value of 0 for the first element of the array. A compiler associates variables x and y with registers r2 and r3, respectively. Assume the starting address of the array is contained in register r4. Translate the C statements below into assembly instructions: a, y = array[0]-x; b. x = array[5]-y; c- array[9] = array[13] + y
