Approach

Approach 1: using static variable

Step-i) create a static variable and initialize with 1
Step-ii) create a empty string
Step-iii) append current value and call the present function by incrementing the variable
Step-iv) repeat step iii till i <= number
Step-v) return the string

Time Complexity: O(n)
Space Complexity: O(n)

Approach 2: without using static variable and recursion

Step-i) create a empty string and append the value i (initially i is equal to 1)
Step-ii) call the present function passing incremented i and number as parameters
Step-iii)repeat step ii till i <= num
Step-iv) return the string

Time Complexity: O(n)
Space Complexity: O(n)
