. MIPS Assembly and Address Alignment (13 points). Write a sequence of MIPS assembly instructions that checks whether the stack pointer is appropriately aligned (i.e., double-word aligned). If it is misaligned, pad the stack so that the stack ends up appropriately aligned (i.e., update the stack pointer's value to increase the size of the current frame/activation record so that it is double-word aligned); otherwise, don't change the stack. Explain what you are doing using comments. [Hint: don't overthink this problem; your answer should be a relatively short sequence of instructions.]
