Question_1:-
The population of North Korea and South Korea are represented in a square matrix, with the upper triangular elements(including the diagonal) representing North Korea and lower Triangular elements(excluding the diagonal) representing South Korea. Kim Jong-un asks you to inform him the current population figures of his country. Note: The elements are in a scale of 1000. 1 means 1000, 2 means 2000 and so on.

Input Description:
Dimensions of the matrix followed by the elements of the matrix

Output Description:
Sum of upper triangular elements

Sample Input :
3 3
1 2 3
3.25 2 3
1.1 1 3
Sample Output :
14000
********************************

a,b = map(int, input().split())
arr = []
count = 0
ar = 0
for i in range(a):
arr.append(list(map(float, input().split())))
for i in range(a):

for j in range(0+ar, b):
count += arr[i][j]
ar += 1
print(int(count*1000))
