Program 31: Consider a string blessing = 'Stay Happy n Healthy'. For each of the five rows of the
following table, write the appropriate slicing statement in the space provided in the table that produces the output
given in the second column.

Assume the string blessing is defined as follows:

blessing = 'Stay Happy n Healthy'
Verified Command

blessing[:6]
blessing[2:10:4]
blessing[3:10]
blessing[-1::-1]
blessing[-3:-12:-2]
