WebApr 12, 2024 · unsigned int n = 11; cout << reverseBits (n); return 0; } Output 13 Time Complexity: O (num), where num is the number of bits in the binary representation of n. Space Complexity: O (1) How about considering even the leading zero bits for the reversal? Another twist to this problem is to reverse all 4 bytes of an integer value. WebIn signed integers, the first bit is the sign bit and the rest are the value in 2's complement notation; so for example a signed char with bit pattern 11111111 would be interpreted as the numerical value -1 while an unsigned char with the same bit pattern would be 255. Most integer types are signed unless otherwise specified; an n-bit integer ... WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined ... the piano brothers music
