LeetCode Problem - Link


A pretty straightforward approach for solving this, we add the adjacent numbers in an array and return the final resultant array


Sequential Approach

/**
 * @param {number[]} nums
 * @return {number[]}
 */
var runningSum = function(nums) {
    // We can skip the first element as it doesn't participate yet
    for(var i=1;i<nums.length;i++){
            nums[i] += nums[i-1]
    }
    return nums
};
