Please Help my output is not getting correct: Reverse Bits question

#1
#2

hello @yashratnani6

a) u need to iterate upto 15 (becuase if u iterate till 31 then it will give u same A)

b) image

this will reset all other bit as well becuase in ur mask only one bit is set and rest all are zero , so when u will take and it will mark other set bit as 0
pls check ur updated code here->

unsigned int Solution::reverse(unsigned int A) {
    unsigned int reversedNum = 0;
    unsigned int mask1=0;
    unsigned int mask2=0;
    for(int i=0;i<=15;i++){
        mask1 = 1<<i;
        mask2 = 1<<(31-i);
        
           
         if( ((A&mask1)>0) && ((A&mask2)==0)){
            A = ((A | mask2) & (~mask1) );
        }else if( ((A&mask1)==0) && ((A&mask2)>0)){
            A = ((A|mask1) & (~mask2) );
            
            }
       
        
    }
    return A;
    
}
