Given an integer element ‘N’, the task is to find the minimum number of operations that need to be performed to make ‘N’ equal to 1.
The allowed operations to be performed are:
- Decrement N by 1.
- Increment N by 1.
- If N is a multiple of 3, you can divide N by 3.
Input: N = 4
4 – 1 = 3
3 / 3 = 1
The minimum number of operations required is 2.
Input: N = 8
8 + 1 = 9
9 / 3 = 3
3 / 3 = 1
The minimum number of operations required is 3.
- If the number is a multiple of 3, divide it by 3.
- If the number modulo 3 is 1, decrement it by 1.
- If the number modulo 3 is 2, increment it by 1.
- There is an exception when the number is equal to 2, in this case the number should be decremented by 1.
- Repeat the above steps until the number is greater than 1 and print the count of operations performed in the end.
Below is the implementation of the above approach:
- Minimum number of given operations required to reduce the array to 0 element
- Count the number of operations required to reduce the given number
- Reduce N to 1 with minimum number of given operations
- Count operations of the given type required to reduce N to 0
- Minimum number operations required to convert n to m | Set-2
- Minimum number of operations required to delete all elements of the array
- Find the minimum number of operations required to make all array elements equal
- Minimum steps required to reduce all the elements of the array to zero
- Minimum operations required to change the array such that |arr[i] - M| <= 1
- Minimum operations required to convert X to Y by multiplying X with the given co-primes
- Minimum no. of operations required to make all Array Elements Zero
- Minimum operations of the given type required to make a complete graph
- Minimum operations required to make all the array elements equal
- Minimum operations required to make every element greater than or equal to K
- Minimum operations required to make all the elements distinct in an array
