What is the purpose of the code, and is there any problem with it? unsigned int f( unsigned n )..

Answer / senthil

f returns the 8's complement of the lower 3 bits of a given number

................................(2's complement of n)&0x07
f(0) => -00000000&00000111 => 00000000&00000111 => 00000000 (0)
f(1) => -00000001&00000111 => 11111111&00000111 => 00000111 (7)
f(2) => -00000010&00000111 => 11111110&00000111 => 00000110 (6)
f(3) => -00000011&00000111 => 11111101&00000111 => 00000101 (5)
f(4) => -00000100&00000111 => 11111100&00000111 => 00000100 (4)
f(5) => -00000101&00000111 => 11111011&00000111 => 00000011 (3)
f(6) => -00000110&00000111 => 11111010&00000111 => 00000010 (2)
f(7) => -00000111&00000111 => 11111001&00000111 => 00000001 (1)
f(8) => -00001000&00000111 => 11111000&00000111 => 00000000 (0)
f(9) => -00001001&00000111 => 11110111&00000111 => 00000111 (7)
f(10) => -00001010&00000111 => 11110110&00000111 => 00000110 (6)
