Given two integers A and B. The task is to find the nearest greater value to B by interchanging the digits of A. If no such permutataion possible then print -1.
Input: A = 459, B = 500
549 is the nearest greater.
Input: A = 321, B = 567
Input: A = 231, B = 125
Prerequisites: All permutations of a string
- Set the minimum value of min1 by using the Integer.MAX_VALUE
- Interchange the digit of A by using above mentioned permutation method.
- Check if the permutataion of A is less than min1 or not. If less then update min1 as A.
- Repeat this for all permutataions of A and find the minimum greater value
Below is the implementation of the above approach :
- Next greater Number than N with the same quantity of digits A and B
- Largest number not greater than N all the digits of which are odd
- Find next greater number with same set of digits
- Next greater number on the basis of precedence of digits
- Largest number not greater than N which can become prime after rearranging its digits
- Count numbers in given range such that sum of even digits is greater than sum of odd digits
- Nearest prime less than given number n
- Round the given number to nearest multiple of 10
- Round the given number to nearest multiple of 10 | Set-2
- Find smallest number with given number of digits and sum of digits under given constraints
- Count of integers in a range which have even number of odd digits and odd number of even digits
- Check whether product of digits at even places is divisible by sum of digits at odd place of a number
- Count of numbers between range having only non-zero digits whose sum of digits is N and number is divisible by M
- Maximize the given number by replacing a segment of digits with the alternate digits given
- Number formed by deleting digits such that sum of the digits becomes even and the number odd
