Given an array of integers, the remaining elements appear two times, except for an element. Please find out this element that appears only once.Note:Your algorithm should be a linear time-of-day complexity.

Given a number 'n', find the smallest number 'P' such that if we multiply all digits of 'P', we get 'n '. the result 'P' shoshould have minimum two digits.
Examples:
Input: n = 36Output: p = 49 // Note that 4*9 = 36 and 49 is the smallest such numberInput: n = 100Output: p = 455// Note that 4*5*5 = 100 and 455 is the smallest such numberInput: n = 1Output:p = 1
