Web10 sep. 2015 · I have to compute the Legendre symbol ( 5 p). If p = 2, it is immediate to see that we have 5 ≡ 1 ( mod 2). let p an odd prime. By quadratic reciprocity we have ( 5 p) = ( − 1) p − 1 ( p 5), so ( − 1) p − 1 = 1 and we have ( 5 p) = ( p 5). Thus, we have to analyze the cases p ≡ 1 mod 5, p ≡ − 1 mod 5 and p ≡ 3 mod 5. WebIf it's p-1, your function should replace that with -1. Here is a fixed version: def Legendre (arr, p): e = (p - 1) // 2 results = [pow (a, e, p) for a in arr] return [ (r-p if r > 1 else r) …
