Program to shift array elements on right side by one position - Array - C Programming

TL;DR

Learn how to perform cyclic rotation or shifting of elements in an array, either to the right or left.

Transcript

hello friends let us look at one of the important programs of arrays we call them as a cyclic rotation of the arrays or shifting the elements of an array by one position when i say that i am supposed to do a shifting operation there are two types of shifting one is right shift and the other is a left shift now how do i carry out this particular tas...

Key Insights

• 🧘 Cyclic rotation involves shifting elements in an array by one position.
• ©️ Right shifting involves copying the last element to a temporary variable and shifting the rest of the elements to the right.
• 🍤 The logic for shifting can be summarized in three steps: copying the outgoing element to temp, shifting the other elements, and putting temp at the first position.
• 🗯️ When performing a right shift, start the loop from n-2 and go towards 0 to shift the remaining elements.

Questions & Answers

Q: What is cyclic rotation in arrays?

Cyclic rotation is the process of shifting the elements of an array by one position.

Q: What are the two types of shifting in cyclic rotation?

The two types of shifting are right shift and left shift.

Q: How do you perform a right shift in cyclic rotation?

In a right shift, the last element is copied to a temporary variable, and then the other elements are shifted to the right.

Q: How does a left shift differ from a right shift in cyclic rotation?

In a left shift, the first element moves to the last position, and the other elements shift to the left.

Summary & Key Takeaways

• Cyclic rotation involves shifting the elements of an array by one position.

• Shifting to the right means the last element moves to the first position, while the other elements shift to the right.

• To perform a right shift, the last element is copied to a temporary variable, and then the other elements are shifted.
