@Hitesh-Kumar-2485183164914830,

https://ide.codingblocks.com/s/220900 Corrected code.

In the given pattern if row number is n (>1), total character is n. First and last character is n-1 and rest are 0.

Thinking about Value to be printed : row number is to be printed each time at the starting of the row and at the end of the row. So, starting of the row is when out cst is 1 and ending of the row when our cst is nst.
