Maximum Sum
Write a program that adds up the largest row sum and the largest column sum from an N-rows *M-columns array numbers.
Input specification:
Input1: Integer for row dimension of the array.
Input2: Integer for column dimension of the array.
Input3: Array elements to be entered in row major.
Output Specification:
Largest row sum + Largest column sum
Example 1:
Input 1: 2
Input 2: 2
Input 3: {1,2,5,6}
Output: 19
Explanation:
Largest row(5,6) + Largest Column(2,6) = 11 + 8 =19
Example 2:
Input 1: 3
Input 2: 3
Input 3: {1,2,3,4,5,6,7,8,9}
Output: 42
Explanation:
Largest row(7,8,9) + Largest Column(3,6,9) = 24 + 18 = 42
Solution in Python:
m=int(input())
n=int(input())
l=[int(x) for x in input().split()]
maxr=0
i=0
while(i<len(l)):
rowsum=0
for j in range(i,i+n):
rowsum+=l[j]
if(maxr<rowsum):
maxr=rowsum
i+=n
maxc=0
i=0
while(i<n):
colsum=0
for j in range(i,len(l),n):
colsum+=l[j]
if(maxc<colsum):
maxc=colsum
i+=1
print(maxr+maxc)
