@sukhwinder9813 Here you need to partition the given number such that each partition contains a number <=26. Say if sample input is 123, then you can partition in following ways:
1|2|3 —> ABC
1|23 -----> AW
12|3 -----> LC
So take input the number in the form of a string so that it is easy to partition.
Following this, try to build a recursive relation and implement on yourself.
