2154. Keep Multiplying Found Values by Two
Problem Explanation
Explanation
To solve this problem, we iterate through the array nums checking if the current value is equal to original. If it is found, we update original to be twice its value. We repeat this process until we either don't find the current original value in nums or reach the end of the array. Finally, we return the updated original.
- Time complexity: O(n), where n is the number of elements in the array
nums. - Space complexity: O(1).
Solution Code
class Solution {
public int keepMultiplyingFoundValuesByTwo(int[] nums, int original) {
for (int num : nums) {
if (num == original) {
original *= 2;
} else {
break;
}
}
return original;
}
