 Left Right Top Bottom Sum 

 Problem Statement 

The program must accept a matrix of size R*C and for each cell the program must print the sum of left, right, top and bottom cells.

 Boundary Conditions 

2 <= R, C <= 20

1 <= Matrix element value <= 10⁵

Input Format

The first line contains R and C separated by a space.

The next R lines, each contains C integers separated by a space.

Output Format

The first R lines, each contains C integers separated by a space.

#include<stdio.h>
#include<stdlib.h>

int getLeftRightTopBtmSum(int r,int c,int i,int j,int a[r][c]){
    int sum=0;
    //Left Cell
    if(j-1>=0){
        sum+=a[i][j-1];
    }
    //Right Cell
    if(j+1<c){
        sum+=a[i][j+1];
    }
    //Top Cell
    if(i-1>=0){
        sum+=a[i-1][j];
    }
    //Bottom Cell
    if(i+1<r){
        sum+=a[i+1][j];
    }
    return sum;
