WebNov 23, 2016 · bash. First we need the biggest integer of the form 2^n (1 bit set followed by zeros). We can do that by shifting left until the next shift makes the number negative, also called "wrap around": a=1; while ( (a>0)); do ( (b=a,a<<=1)) ; done. Where b is the result: the value before the last shift that fails the loop. WebLeft shift operator is a bitwise shift operator in C which operates on bits.
