Given a number N, we have to find the minimum number of palindromes required to express N as a sum of them.
Input: N = 11
11 is itself a palindrome.
Input: N = 65
65 can be expressed as a sum of three palindromes (55, 9, 1).
We can use Dynamic Programming to solve this problem. The idea is to first generate all the palindromes up to N in a sorted fashion, and then we can treat this problem as a variation of the subset sum problem, where we have to find the size of the smallest subset such that its sum is N.
Below is the implementation of above approach:
- Minimum number of palindromes required to express N as a sum | Set 2
- Minimum number of given powers of 2 required to represent a number
- Minimum number of given operation required to convert n to m
- Minimum number of changes required to make the given array an AP
- Minimum number operations required to convert n to m | Set-2
- Minimum number of operations required to reduce N to 1
- Minimum number of primes required such that their sum is equal to N
- Minimum number of mails required to distribute all the questions
- Minimum number of operations required to sum to binary string S
- Minimum number of bottles required to fill K glasses
- Minimum number of integers required to fill the NxM grid
- Minimum number of given moves required to make N divisible by 25
- Minimum number of given operations required to reduce the array to 0 element
- Minimum number of given operations required to make two strings equal
- Minimum splits required to convert a number into prime segments
