$2\mathrm{.}4$ Draw a ladder program which counts the pulses on X$1.$ The program will set the output Y $0$ if the number of pulses is greater than $19$ and less than $29.$ The counter will be reset to zero at the rising edge of input X$2.$ You may assume that there will be a pulse on X $2$ within each $1200$ pulse of X$1$
