barxatty [35]

Answer:

Function sparse code is

def sparse(a):

rl = []

cl = []

for i in range(0,len(a)):

rl.append(a[i][1])

cl.append(a[i][2])

r = max(rl)

c = max(cl)

s = []

k = 0

for i in range(0,r+1):

s.append([])

for j in range(0,c+1):

if (i==a[k][1]) & (j == a[k][2]):

s[i].append(a[k][0])

k = k+1

else:

s[i].append(0)

return s

def main():

k = sparse([[3,1,2],[4,5,3]])

print(k)

if __name__ == '__main__':

Which of the following bit patterns represents the value -9 in two’s complement notation?
nadya68 [22]

Answer:

B. 11110111

Explanation:

Binary representation of number 9 = 00001001

Binary representation of -9 would involve calculating the twos complement representation of 00001001

First we compute the ones complement of this number by reversing the bits.

00001001 => 11110110

Next we calculate the twos complement representation by adding 1 to the ones complement.

11110110+1 = 11110111

So the final representation is 11110111.
