I need to replace a Math.pow in Java with bitshift.
for (int i = n - 1; i >= 0; i--)
Math.pow(16, n - i - 1)
Where n is the length of a hex number.
13304fb would mean n= 7.
It’s basically converting hex to decimal.
Now I need to replace that Math.pow with Bitshift. I cant figure it out, because the n could be as large as it wants to be.
16^(n - i -1)=2^(4 * (n - i -1))2^x=1 << x.Therefore:
16^(n-i-1)=1 << (4 * (n -i -1))(Using the
^symbol to mean “to the power of”, not XOR)
