The answers are as follows:
a) F(A, B, C) = A'B'C' + A'B'C + A'BC' + A'BC + AB'C' + AB'C + ABC' + ABC
= A'(B'C' + B'C + BC' + BC) + A((B'C' + B'C + BC' + BC)
= (A' + A)(B'C' + B'C + BC' + BC) = B'C' + B'C + BC' + BC
= B'(C' + C) + B(C' + C) = B' + B = 1
b) F(x1, x2, x3, ..., xn) = ∑mi has 2n/2 minterms with x1 and 2n/2 minterms
with x'1, which can be factored and removed as in (a). The remaining 2n1
product terms will have 2n-1/2 minterms with x2 and 2n-1/2 minterms
with x'2, which and be factored to remove x2 and x'2, continue this
process until the last term is left and xn + x'n = 1
A strong password obeys some password rules, such as:
- minimum length
- using characters from different classes (uppercase, lowercase, numbers, typographic characters)
Your safest bet these days is to use a password manager and have it generate one for you, so that hackers can not guess it by understanding humans' predictable mind. ;-)
Answer:
CLS
M=2
SUM=0
DO WHILE M<=50
SUM=SUM+M
M=M+2
LOOP
PRINT " The sum of all even numbers between 1 and 50 is"; sum
Answer:
Description: Write a MASM 32bit program with a loop and indexed addressing that calculates the sum of all thegaps between successive array elements. The array elements are doublewords, sequenced in nondecreasing order.
