sqrt log sin

An evil professor has just assigned you the following problem. A sequence is defined by the following recurrence: x0 = 1 xi = x √ +x⌊ln(i)⌋+x 2 ⌊i− i⌋ ⌊isin (i)⌋ Determine x1000000. Input Input consists of a number of lines, each containing one integer, a value of i, no less than zero and no greater than one million. Input is followed by a single line containing the integer ‘-1’. This last line is not a value of i and should not be pro- cessed. Output For each value of i in the input (but not the final ‘-1’), output the corresponding value of xi modulo 1000000. Sample Input 0 -1 Sample Output 1
