hi @rathidevesh906_1dcc73a061c159bb,
you r printing 0 or 1 at each cell instead traverse all at once and if u found key anywhere make one ans variable and make it true which initially is false
when u come out of loop if the ans is true print 1 else print 0
also its n*m not m*n
and a[i][j] == key not a[i][j] = key
check here ive updated and commented https://ide.codingblocks.com/s/661263
