94. Ravi and Rupali are asked to write a program to sum the rows of a 2X2 matrices stored in the array A.
Ravi writes the following code (Code A):
for n = 0 to 1
sumRow1[n] = A[n][1] + A[n][2] end
Rupali writes the following code (Code B):
sumRow1[0] = A[0][1] + A[0][2]
sumRow1[1] = A[1][1] + A[1][2]
Comment upon these codes (Assume no loop-unrolling done by compiler):

95. If the Arithmetic mean is 34 and geometric mean is 16 then what is greates number in that series of numbers?
Answer: 64
Explanation:Lets assume two numbers be x, y;
Arthmetic mean=34=>( x+y)/2=34
=> x+y=68
geometric mean=16=>(xy)^(1/2) = 16
=> xy=16*16=256
By trail and error 16*16=64*4
And 64+4/2=34
So the greatest number int that series is 64.
