hello
I,ve wrote a program but it doesn,t work correctly
please help me
i want to sort some strings based on the number that should be entered at first of each string for example the strings that you enter should be in this form:
12_hello
it means you should enter a number and then _ then a string
for example if you enter
5_allow
4_how
23_hi
the output should be
4_how
5_allow
23_hi

but my program can't do this
i will write my program here

please correct it for me
thanks in advance
