Input: 3 2 7 9 4 2 5 9 2 4 1 6 2 3 9 6 9 8 3 1 6 4 2 7 9 4 8 2<\/p>\n\n\n\n
Step I: All such 2\u2019s which is immediately preceded by an even number and immediately followed by a prime number is to be placed immediate right of that prime number.<\/p>\n\n\n\n
Step II: All digits greater than 5 are subtracted by 1, whereas all digits less than 5 are increased by 1.<\/p>\n\n\n\n
Step III: Add \u20182\u2019 to all prime numbers which are immediately followed by an even number. Step III is the final output.<\/p>\n\n\n\n
