In this blog we are going to solve a problem on codeforces. You can read the problem statement here.
If the current position is (0, 0, 0) then body will be in equilibrium if and only if all the sum of the resolution is zero i.e.
x1 + x2 + x3 + … + xn = 0
y1 + y2 + y3 + … + yn = 0
z1 + z2 +z3 + … + zn = 0
So to solve this problem we have to find the sum of all the resolution and then print the output.
So the code for this solution is : –
n = int(input()) vec =  for i in range(n): vec.append(list(map(int,input().split()))) sum1, sum2, sum3 = 0, 0, 0 for i in range(n): sum1 += vec[i] sum2 += vec[i] sum3 += vec[i] if sum1 == 0 and sum2 == 0 and sum3==0: print("YES") else: print("NO")
