@prasanth I know this solution...Try giving with constraints
specified ...
only following operations are available...
SHR reg1, op1
ADD reg1, op1
AND reg1, op1
NOT reg1.

let a and b be the two numbers
int temp,result;
temp=a-b;
//if temp is -ve,then its MSB will be 1..else it ll be 0..so
temp=temp (131);
//now temp either holds 0(if temp is +ve) or a -ve no(if temp is -ve)
result=a - temp(a-b);
//now result contains the required value since a-(a-b)=b
printf(%d,result);

Two registers A and B. Initial Contents of the registers are unknown.
Write a program to find MAXINT - The maximum positive unsigned integer
The instructions available are:
SHR reg1, op1
ADD reg1, op1
AND reg1, op1
NOT reg1.
Op1 may represent any number or register.
(Hint: The Shift operation is a logical shift, not arithmetic shift.)
..solution plz .. i tried but unable to arrive
