hi @shraddhamishra812003_b58bd74465a696b0
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 3 2 
         3 4 5 4 3  
           2 3 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.
  • Given pattern is seen as first we need to work for spaces and then for the numbers in each row.
  • Numbers are first increasing till the mid element and then decreasing till end of the row.
  • Thus, do the work of first spaces and then for numbers .
  • And then change variables accordingly for next iterations.

Always think of first row and then work for the next iteration and repeat the work total number of row times. That’s how you can solve any problem related to pattern.
