I can't understand that how this answer came, can somebody explain me? |

Vineeth said: (Nov 26, 2010) | |

helo jasmin..here is the explanation write numbers in binary 0000 0001 0010 .... .... .... 1111 so we want to find out 11&9. ie 1001 1000 ---- 1000----->9 using this value we can find y in successive operations as explained. i think its a good question..thank you |

Jaz said: (Dec 10, 2010) | |

Well anyone make more clear. |

Sumit said: (Dec 24, 2010) | |

Please explain this clearly and complete. I can't understand what is happning. |

Suresh said: (Mar 26, 2011) | |

11 in binary form is 1011 9 in binary form is 1001 so 11&9=1001 ie equals 9 and y=x^3 == x value is 9 then y=9^3==1001(ie 9 binary value) 0011(ie 3 binary value) so y=1011 ie equals to 11 then y|12 is equals to 11|12 == 1011 1100 ==15 so the =answer is 15 |

Do smart work by looking at options we can say tht first three ans are lesser than 12 while doing OR operation the value will automatically increase. |

Sudarshan said: (Jun 19, 2011) | |

1001 = (x=9) 0011 = 3 1010 = (y=9^3) 1100 = 12 1110 = y|12 |

What the function ^ is does ? |

Jaishriram said: (Dec 19, 2011) | |

Mansi Jain: ^ is EX-OR function, which means if toggle answre is 1 else 0 eg: 9^3 == 1001 0011 ------ 1010 == number 10 ook when the binary digit are same, we get 0 as resut, when they toggle we get 1. |

Satish said: (Feb 1, 2012) | |

Binary of(11)=1011 Binary of (9)=1001 Perform & ------ Result X=1001 which is in decimal(9) Now X^3 where x=1001 Binary of(3) = 0011 Perform ex-or ------ Result Y=1010 which is in decimal(10) Now perform (Y|12)=1010 Binary of (12) = 1100 Perform or(|) ----- Result = 1110 which is in decimal (14). Hence the ans is 14. |

Thanks Sudarshan and Satish. |

11 == 1011 9 == 1001 & (AND) ---------- 9 == 1001 3 == 0011 ^ (XOR) ---------- 10 == 1010 12 == 1100 | (OR) ---------- 14 == 1110 |

8421 1011 1001 & (Bitwise And - Set bit if both bits set) ---- 1001 (9) 1001 0011 ^ (Bitwise Exclusive Or - Set bit if ONLY one bit is set) ---- 1010 (10) 1010 1100 | (Bitwise Or - Set bit if either bit is set) ---- 1110 (14) |

John said: (Jan 24, 2015) | |

8421 1011 1001 ==== 1001=9 0011 ==== 1010=10 1100 ==== 1110=14 |

Thanks @Satish. |

Rashmi said: (Aug 7, 2016) | |

8421. 1011 1001 & (Bitwise And - Set bit if both bits set). ---- 1001 (9) 1001 0011 ^ (Bitwise Exclusive Or - Set bit if ONLY one bit is set). ---- 1010 (10) 1010 1100 | (Bitwise Or - Set bit if either bit is set). ---- 1110 (14) |

Thanks @Rashmi. |

Step 1) 11 & 9. 11 -> 1011. 9 -> 1001. & -> work like and operator. 1011 1001 ---------- 1001. Step 2) X ^ 3. ^ -> XOR operator. 9 -> 1001 3 -> 0011 ------------- 1010. Step 3) 12 | X x -> OR operator. 1100 1010 --------- 1110 1110 -> 14. |

Accel said: (Nov 29, 2016) | |

Thanks a lot, @Rashmi. I didn't understand why 1 or 1 = 0, but you covered that up! |

Sachin J said: (Dec 17, 2016) | |

Thank you @Jaishriram. |

Sunny Deol said: (Jan 21, 2017) | |

Agree @Suresh. I think 15 is the correct answer. |

Divyadharshini said: (May 16, 2017) | |

Thanks a lot @John. |

Ranjitha said: (Oct 26, 2017) | |

Thanks for this. |

Buck said: (Oct 31, 2017) | |

Very well explained @ Rashmi and @Suresh. |

Ashu said: (Dec 6, 2017) | |

What should be done when 1100|0011? How the String is done? |

Raghavendar said: (Feb 20, 2018) | |

int x=9&11; & ---->And operation means both are true then output is true otherwise false so 9----->1001(binary form) 11---->1011 ---------------------------------------- 1001 so it's----->9 ------------------------------------------------ y=x^3 ^ ------->XOR operation so if both inputs are same then output is false otherwise false So, x value is 9 binary is----1001. y=1001^0011=1010 (decimal is 10) then; y|12 -----------> |-- OR operation means if both inputs are false then the output is false otherwise true. y value----->1010 12 binary-> 1100 ---------------------------------- 1110 ------->14. So the answer is 14. |

Prudhvi said: (Feb 28, 2018) | |

Well explained, thanks @Jitesh Powankar. |

Dheeraj Reddy said: (Sep 17, 2018) | |

11= 1101. 9 = 1001. 9 = 1001. 3 = 0011. 10 = 1010. 12 = 1100. 14 = 1110. |

Manoj said: (Oct 5, 2018) | |

XOR means, the output will be 1 if both the input are exclusive i.e. both the input should be different for example (1, 0) (0, 1) so this gives output 1. Hence output of (1, 1) (0, 0) is 0. |

Sneha Sonawane said: (Dec 15, 2018) | |

x=11&9 ie 1011(11) & 1001 (9) =1001 (9) //Binary conversions therefore now x=9; y=x^3 ie 9^3 (^ is Ex OR operation) 1001^0011= 1010 (10) // Binary conversions therefore now y=10;. y|12 ie 10|12 ( | is OR operator) 1010 | 1100 =1110 (14) ///Binary conversions therefore now y=14; |

Keerthana said: (Jul 8, 2019) | |

Why we are choosing 9 as value for X? There is an another value 11. |

Atul said: (Oct 9, 2019) | |

For know about operate: For AND operate 1,1 ---result will be 1 like (1,1) --->1 (0,0)--->0 (0,1)--->0 (1,0)--->0 For OR operate 0,0----result will be 0 like (1,1) --->1 (1,0) --->1 (0,1) --->1 (0,0)--->0 for EXor operate 0,0----result will be 0 and 1,1 ---result will be 1 ,other than 1 (0,0) --->0 (1,0) --->1 (0,1) --->1 (1,1) --->0 -------------------------------------------------------- --------------------------------------------------------- Binary value Decimal value 1100 12 1001 9 1011 11 0011 3 1001 9 1011 11 =========== 1001--------(And operate) result is 1001 which is equals to = 9 in decimal value -------------------------------------------------------------------------- 1001 9 ( decimal value) 0011 3 ( decimal value) -->9^3 1001 0011 =========== 1010 ...>(EXor) result is 1010 which is equals to = 10 in decimal value -------------------------------------------------------------------------- 1100 12 ( decimal value) 12 | X | -> OR operator. 1010 1100 =========== 1110 (OR operator) result is 1110 which is equals to = 14 in decimal value |

11 == 1011 9 == 1001 & (AND) ---------- 9 == 1001 3 == 0011 ^ (XOR) ---------- 10 == 1010 12 == 1100 | (OR) ---------- 14 == 1110. |

Arun said: (Mar 23, 2021) | |

11=1011 9= 1001(binary value) First condition (int x = 11 & 9;) &-And operator check both are true else return false so X take 9. X=9. Second condition (int y = x ^ 3;) ^ power operator X=1001 ^ 3=0011. Outcome is 1010 1010 is a value of 10. Third condition( y | 12 ) is 0r operator, (10 |12) in the binary value. 10 = 1010 ( 0r operator). 12=1100. Output is 1110 is a value of 14. |
