Write a c function for :

int signedBits0through5(int v)

// return the signed value in bits 0 through 5

//Example input: 0x3fa, example output: 0xfffffffa

//Any extracted bits should be returned in the lowest bits of the return value. For example, in a function unsignedBits6through9, if bits 0110 were extracted from the value, then 0110 with 28 leading zeros should be returned (32-bit integers).
