Starting from 1, generate a sequence - which denotes the operations used to reach the target
	* multiple by 2
	* floor division by 3

Example 1:
# target = 1
# output: ""
# explanation: 1 (target) = 1, no operations needed

Example 2:
# target = 2 
# output: "*"
# explanation: 2 (target) = 1 * 2 

Example 3:
# target = 8 
# output: "***"
# explanation: 8 (target) = 1 * 2 * 2 * 2 

Example 4:
# target = 10 
# output: "****/*"
# explanation: 10 (target) = 1 * 2 * 2 * 2 * 2 // 3 * 2

Example 5:
# target = 3 
# output: "****/*/"
# explanation: 3 (target) = 1 * 2 * 2 * 2 * 2 // 3 * 2 // 3
