Array rotation is a common computer programming operation that involves shifting the elements of an array by a specified number of positions. This can be done in two ways:<\/p>\n
Array rotation is the process of rearranging the elements of an array by shifting them by a specified number of positions.<\/p>\n
The array elements are shifted to the left by a certain number of positions in left rotation, and the elements that "fall off" the left end of the array are added to the right end of the array. If we take an array [1, 2, 3, 4, 5] and rotate it by two positions, we get the array [3, 4, 5, 1, 2].<\/p>\n
Let us now look at how to rotate the array by d positions to the left. The steps are as follows:<\/p>\n
function rotate_array(arr, n, d):\n temp <- new array of size d\n for i from 0 to d-1:\n temp[i] <- arr[i]\n for i from d to n-1:\n arr[i-d] <- arr[i]\n for i from 0 to d-1:\n arr[n-d+i] <- temp[i]<\/code><\/pre>\nC++ Code for Array Rotation by D Positions to the Left.<\/h3>\n\t\t\t\t\t\t
