Adding this tag will result will not only lead to a break statement to exit within the
Ministry for the statement (that is, using a variable j loop), but also withdraw from the outside for the statement (that is, using a loop variable i).

continue statement forces continue the cycle - to exit the inner loop, the outer loop.
