mysql - want to convert hex to binary which gives answer is more than 64 bits -


i want convert hex binary

if use conv function gives wrong result if result contains binary value greater 64 bits

i want convert below hex no binary

hex b3c935bb3667c964db1381db72fd8c897023879b19ab42e937839983cece465d18b719b8a37059ead4152298396f78743aa48245d1d80b899d19bd4e8217c963a187e97d028726c2

if use conv function gives result like:

 select conv('b3c935bb3667c964db1381db72fd8c897023879b19ab42e937839983cece465d18b719b8a37059ead4152298396f78743aa48245d1d80b899d19bd4e8217c963a187e97d028726c2 ',16,2);

output:

1111111111111111111111111111111111111111111111111111111111111111

but want answer :

101100111100100100110101101110110011011001100111110010010110010011011011000100111000000111011011011100101111110110001100100010010111000000100011100001111001101100011001101010110100001011101001001101111000001110011001100000111100111011001110010001100101110100011000101101110001100110111000101000110111000001011001111010101101010000010101001000101001100000111001011011110111100001110100001110101010010010000010010001011101000111011000000010111000100110011101000110011011110101001110100000100001011111001001011000111010000110000111111010010111110100000010100001110010011011000010

b3c935bb3667c964db1381db72fd8c897023879b19ab42e937839983cece465d18b719b8a37059ead4152298396f78743aa48245d1d80b899d19bd4e8217c963a187e97d028726c2 can't treated hexademical value, it's far more bigger maximum 64-bit integer value equivalent (7fffffffffffffff)16.

mysql gives correct result of (7fffffffffffffff)16 = (0111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111 1111)2. use string binary conversion instead if achive result mentioned.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
