Write code to implement the following function: Generate mask indicating leftmost 1 in x. Assume w=32. For example OxFF00-> 0x8000, and 0x6600 --> 0x4000. * If x=0, then return 0. int leftmost_one(unsigned x): Your function should follow the above bit-level integer coding rules, except that you may assume that data type int has w=32 bits. Your code should contain a total of at most 15 arithmetic, bit-wise, and logical operations
