WebIn this solution besides the rotate the element one by one we will rotate the array in sets. Where the number of sets is equal to GCD of n (array size) and K (position to rotate array elements). Suppose arr is an integer array and size is 7, we want to rotate it by 2. So here n=7 and k =2 and array elements are {1,2,3,4,5,6,7}; Web12 jun. 2024 · function rotate2(nums, k) { k = k % nums.length; let arr = []; for (let i = 0; i < nums.length; i++) { arr[ (i + k) % nums.length] = nums[i]; } //... } Now, arr will be the rotated array that we want. However, in this problem, we should be modifying the nums array, so we have to set each index in nums equal to the value at that index in arr.
