Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    int cs=0;
    int ans=0;
    for(int i=0;i<n-1;i++){
        cs^=mem[i];
        //printf("%d\n",mem[i]);

    }
    
    if (cs==mem[n-1]){
        ans=1;
    }
    // Write your XOR scan logic here
    return ans;
}

int main() {
    int n, arr[100];
    scanf("%d", &n);
    
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int result = validate_checksum(arr, n);
    printf("%d", result);

    return 0;
}
