Approach


Step-i) get the length of the given string
Step-ii) create a empty string new_time
Step-iii) if last second character of the string is P go to next step else go to vii
Step-iv) get the hour part from the string
Step-v) if hours equal to 12 append 00 to new_time and copy the rest of the string
Step-vi) else copy the entire string and return the time
Step-vii) get the hours part from the string
Step-viii) add 12 to the hours part and append to the new_time
Step-ix) add rest of the string as it is to the new_time
Step-x)return the string

Time Complexity : O(1)
