**Tutorial 26:**- (1) Add an additional label
`superior`to each row indicating whether (`1`) or not (`0`) the selection sort algorithm (`T0`) is faster than the insertion sort algorithm (`T1`). (2) Same as (1) but use an`iff(exp, then, else)`to indicate the superiority with`yes`or`no`. (3) Compute the difference`diff`in running time between`T0`and`T1`.**Hint:**Since all values in a*sus*file are interpreted as strings you will have to convert them to a number type,*e.g.*,`float`, before arithmetic operations can be used. (4) Use the built-in string formatting to format`diff`such that the output is an absolute value of (3) width 6 rounded up after the first decimal place. **Solution:**-

(1)`sus2text superior='float(T0)<float(T1)' n T0 T1 type < out.sus`

(2)`sus2text 'superior=iff(float(T0)<float(T1),"yes","no")'`

n T0 T1 type < out.sus

(3)`sus2text 'diff=float(T0)-float(T1)' n T0 T1 type < out.sus`

(4)`sus2text --add 'diff="%6.1f"%abs(float(T0)-float(T1))'`

n T0 T1 type < out.sus

The `--add` in the last line is not necessary. It's just to show
a variation.
