Hollow rhombus pattern

#1

Not getting the same pattern

#2

hi @kumarakash121005
In Pattern Question, there is a common method which we teach in course viz, taking nsp, nst, csp, cst and row variables.

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.

nst = (n/2 + 1), cst = 1, rows = 1, nsp = -1,total rows = n;

  • The given pattern is seen as first stars then spaces and then stars .So for each row do the work of stars first , then that of spaces and then that of stars. And then change the variables accordingly for next iterations.
  • But this work will not help u to pass the test cases as there will be 1 extra star in the first line and last line. For e.g.,
       * * * * * *  //Extra star
       * *   * *
       *       *
       * *   * *
       * * * * * * // Extra Star
  • To handle this condition all you need to do is run your second look 1 time less only when control is in first and last line.
    if(rows == 1 || rows == n) cst = 2;
