Explain the rationale of using hexadecimal notation by computer programmers. (4 marks). b. What generalizations can you draw about converting a number from one base to a power of that base, e. g., from base 3 to base 9 (32 ) or from base 2 to base 4 (22 ) or base 8 (23 )? (3 marks) c. Present an overview of the IEEE 754 standard for floating-point representation. In your presentation, describe the rationale behind IEEE 754 standard and a demonstration with an example of converting a real number to IEEE 754 standard and vice versa. (7 marks)

Problem 1 - hashing we would like to use initials to locate an individual. for instance, mel should locate the person mark e. lehr. note: this is all upper case. generate a hash function for the above using the numbers on your telephone. you know, each letter has a number associated with it, so examine your telephone keypad. generate 512 random 3 letter initials and take statistics on a linked list array size 512 to hold this information report how many have no elements, 1 element, 2 elements, does this agree with the hashing statistics distribution?
