### Code

```ip = [int(i) for i in raw_input().split()]
lennot = []
for i in range(ip[1]):
lennot.append([int(j) for j in raw_input().split()])
nodes = [1]
cpt = {1: (0, 1)}
while 1:
l = [lennot[i] for i in range(len(lennot)) if lennot[i][0] in nodes]
m = min([cpt[i[0]][1]*(i[2])+cpt[i[0]][0] + (ip[0]-i[1]) for i in l])
for i in l:
if cpt[i[0]][1]*(i[2])+cpt[i[0]][0] + (ip[0]-i[1]) == m:
nodes.append(i[1])
cpt[i[1]] = (cpt[i[0]][1]*(i[2])+cpt[i[0]][0], cpt[i[0]][1]^1)

if ip[0] in nodes:
print cpt[ip[0]][0]
quit()
