Question

Write an assembly language program in a file called hw6.asm. The program will take a number specified in memory and compute the integer squareroot of the number. This is the integer that when squared will come the closest to the given number. For example: i squareroot (94) = 10;since 9^2 = 81 and 10^2 = 100 i squareroot (123) = 11;since 11^2 - 121 and 12^2 = 144 The integer squareroot computed should be placed in memory. The general algorithm to compute the integer squareroot is: x = 0; x_square = 0; while (x_Square
