Root to leaf path sum equal to a given number

WebConsider each root to leaf path as a number. For example: 1 / \ 2 3 The root to leaf path 1->2 represents the number 12. The root to leaf path 1->3 represents the number 13. Your task is to find the total sum of all the possible root to leaf paths. In the above example, The total sum of all the possible root to leaf paths is 12+13 = 25 WebGive a linear time algorithm to find the shortest simple path in T. The length of a path is the sum of the weights of the edges in the path. A path is simple if no vertex is repeated. Note that the endpoints of the path are unconstrained.
