WebGiven a binary integer value x, the most significant 1 bit (highest numbered element of a bit set) can be computed using a SWAR algorithm that recursively "folds" the upper bits into the lower bits. This process yields a bit vector with the same most significant 1 as x, but all 1's below it. Bitwise AND of the original value with the complement ... WebDec 29, 2024 · 2 Answers. If you're using the FFT and iFFT to perform fast convolution, yes, you can do it in-place and you can do without bit-reversing in the sample processing, but …

The question is to write a function to reverse a vector so v= [1 2 3] becomes v= [3 2 1] It must be recursive. So my idea how to write this function is start off with d=1 the last digit of w, the output, is equal to the first digit of v the input. so thats what I wrote.
