Make an ideal Pyramid by printing letters of a given String

Given a string str, the duty is to print an ideal pyramid by printing the characters of the given string.

Examples:

Enter: str =  “GEEKSFORGEEKS”
Output:
        G 
    E  E  Okay 
S  F  O  R  G

not together with  E Okay S as a result of they make our pyramid imperfect. i.e.

           G 
        E  E  Okay 
    S  F  O  R  G
E  Okay  S  

Enter: str = “PyramidOfStrings”
Output: 
            P 
         y  r  a 
    m  i  d  O  f 
S  t   r   i   n  g   s 

Method: To unravel the issue observe the above concept:

• Discover the rows as much as which an ideal pyramid could be made.
• After discovering the rows and variety of parts used within the string, implements the nested loop until that row.
• Take a pointer that traverses the string and prints the next character.

Beneath are the steps for the above method:

• Initialize a variable say n to retailer the size of the string.
• Initialize two variables x and ele, the place x will retailer the variety of parts in a selected row and ele will retailer the variety of complete parts used from string until that row as much as that row.
• Initialize variable rows as much as which the outer loop will run.
• There are 2 internal loops one for printing the beginning areas of each row and one other row for printing the character.
• Take a pointer ch that traverses the string and prints the next character.
• In each nth row there are 2*row-1 parts So print the character in a row till ok != 2*row-1.

Beneath is the implementation of the above method:

      P 
    y r a 
  m i d O f 
S t r i n g s 

Time Complexity: O (rows*x),  the place rows are the entire variety of rows and x is the entire variety of parts in a selected row.
Auxiliary Area: O(1)
