Multiplication Table

Problem Description

The most classic template problem for nested loops: the 9 x 9 multiplication table.

The outer loop enumerates the row $i$ (from $1$ to $9$) and the inner loop enumerates the column $j$ (from $1$ to $i$), so each row prints $i$ expressions. The $j$-th expression of row $i$ is formatted as j*i=product; for example, row 3 is:

1*3=3 2*3=6 3*3=9

Expressions on the same row are separated by a single space, and there must be no trailing space at the end of a line.

Input Format

This problem has no input.

Output Format

$9$ lines: the complete multiplication table, following the rule above.

Sample Input

(none)

Sample Output

1*1=1
1*2=2 2*2=4
1*3=3 2*3=6 3*3=9
1*4=4 2*4=8 3*4=12 4*4=16
1*5=5 2*5=10 3*5=15 4*5=20 5*5=25
1*6=6 2*6=12 3*6=18 4*6=24 5*6=30 6*6=36
1*7=7 2*7=14 3*7=21 4*7=28 5*7=35 6*7=42 7*7=49
1*8=8 2*8=16 3*8=24 4*8=32 5*8=40 6*8=48 7*8=56 8*8=64
1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81

Constraints

No input; just print the table.

Hint: the inner loop's upper bound is $i$, not $9$ — row $k$ prints exactly $k$ expressions. Do not write i*j= instead of j*i=; the wrong format is judged WA.
