@thakurboy_24 This also an approach :
In Pattern Question, there is a common method which we teach in course viz, taking nsp, nst, csp, cst and row variables.

Pattern Hack : Always first Try to first print pattern by ignoring the value to be printed then accommodate your value in that pattern. For e.g.,

                        1 
                    2 1   1 2 
                3 2 1       1 2 3 
            4 3 2 1           1 2 3 4 
                3 2 1       1 2 3 
                    2 1   1 2 
                        1

View it as:-

                        * 
                    * *   * * 
                * * *       * * * 
            * * * *           * * * * 
                * * *       * * * 
                    * *   * * 
                        *

Short Info about the variables:-

1. nsp (number of spaces)-> Number of spaces in very First Line of the pattern.
2. nst (number of stars)-> Number of stars in very first line of the pattern.
3. csp (counter of spaces)-> counter of spaces that will print the required number of spaces and will be initialized with 1 and incremented upto nsp.
4. cst (counter of stars)->  counter of spaces that will print the required number of stars and will be initialized with 1 and incremented upto nst.
5. rows -> It will be initialized with 1 and will go upto the total number of rows in the pattern.

–Input N is the number of rows.Given pattern is seen as first spaces ,then numbers ,then spaces and then numbers again. Till middle row, number of numbers in one batch in a row is equal to row number. After middle row, number of numbers decreases each time by 1.The max value in the pattern is in the middle row which is (N/2 +1).

–So do the work of spaces first ,then that of numbers in decreasing order, then that of spaces and then that of numbers in increasing order.
