When multiplying an elliptic curve point P by a positive integer n, it can be done in O(log n) time by doubling an accumulator and adding P according to the bit pattern of n. For example, 6P can be expressed as ((0*2+P)*2+P)*2. In the format shown above, show the sequence of doubles and adds, from left to right, needed to compute 11P. 11 in binary is 1011. Autograder format: Begin with 0*2. After each +P close a parentheses (don't forget the opening parentheses) and after each *2 do not insert a

Question
When multiplying an elliptic curve point P by a positive integer n, it can be done in O(log n) time by doubling an accumulator and adding P according to the bit pattern of n. For example, 6P can be expressed as ((0*2+P)*2+P)*2.
In the format shown above, show the sequence of doubles and adds, from left to right, needed to compute 11P. 11 in binary is 1011.
Autograder format: Begin with 0*2. After each +P close a parentheses (don't forget the opening parentheses) and after each *2 do not insert a close parentheses. Because of the order of operations these are the only parentheses needed. Do not insert any other parentheses or any spaces. Hint: there should be exactly three close parentheses.
