*/

/*

REMEMBER : We always design logic according to the pattern.

LOGIC:

Consider the diagonal to be rows and a single line to be column.

Number of loops required = 2

( since we have rows and columns. 1 loop for row and 1 loop for column. )

It would be a nested loop since Number of columns depends on Number of rows.

Outer loop will be for rows and inner loop will be for columns.

outer loop "i" runs from 5 to 1 since we have 5 rows.

We run the "i" loop in decreasing order ( i.e from 5 to 1 )

since rows is in increasing order(5 4 3 ... 1 diagnol value)

Notice in above pattern Number of columns = Position of rows

( i.e 1st row has 1 column, 2nd row has 2 column, 3rd row has 3 columns and so on )

so we run the "j" loop i.e the inner loop from 5 to i.

We run the "j" loop in decreasing order ( i.e from 5 to i )

since column is in decreasing order ( 5 4 ... i single line value )

We print "value" in the inner loop

since number of columns = number of "value" to be printed.

NOTE : WE CAN PRINT ANYTHING WHICH WE WANT. ( for ex : printf("%d",j) or printf("%d",i) or anything according to pattern.

Lastly after one rotation (completion) of inner loop we need to go to the next line so we use printf("\n") statement after closing the

inner loop and before closing the outer loop.
