Question
this my code to complete question in the picture but when I run it with 96 get 64 which is value of significant bit
can you change it to get answer in example which should be
greatestBitPos(96) = 0x40
can you provide it with example of output
int greatestBitPos(int x) {
int mask = x;
mask |= mask >> 1;
mask |= mask >> 2;
mask |= mask >> 4;
mask |= mask >> 8;
mask |= mask >> 16;
mask &= ~(mask >> 1);
return mask;
}
int mask = x;
mask |= mask >> 1;
mask |= mask >> 2;
mask |= mask >> 4;
mask |= mask >> 8;
mask |= mask >> 16;
mask &= ~(mask >> 1);
return mask;
}
