Don't understand how to even start this, help please

There are several bitwise operators to help manipulate bits:

& - Operates on the corresponding bits of two strings of bits. The result is a 1 if both bits were 1, 0 if not.

| - Operates on the corresponding bits of two strings of bits. The result is a 1 if either bit was 1, 0 if not.

^ - Operates on the corresponding bits of two strings of bits. The result is a 1 if only one bit was 1, 0 if not.

>> (number) - Operates on one string of bits. Shifts all bits to the right equivalent to the number provided.

~ - Operates on one string of bits. Inverses all of the bits.

Consider variable string1 = 0x12345678 and variable mask = 0xF

Fill in the missing value (???) by inputting what it should be in the Solutions boxes adjacent to the respective Task below. Each Task is distinct so earlier tasks have no bearing on the following ones (updating string1 will only be for that one task). You are not allowed to introduce new variables or strings of bits. Task Solution 0x8 = string1 ??? mask Ox01234567 = string1 >> ??? 0x12345000 = string1 >> ??? > ???)??? mask 0x92345678 = ((mask & string1)
